Full transcript

1. 0:00Hey everybody, welcome to the last video
2. 0:04of the combat tutorial series. Um, today
3. 0:09I'm just going to be fixing a couple
4. 0:11more bugs and issues with the combat and
5. 0:13then uh going over all the scripts and
6. 0:16then playing the game, showcasing it for
7. 0:18youall. Um, so basic, so essentially I
8. 0:21decided to just open source the whole
9. 0:23thing once I hit around 600 subs and
10. 0:26we're getting pretty close, which is
11. 0:28crazy considering
12. 0:30that I've I've just gotten so many
13. 0:33subscribers within the past couple
14. 0:34weeks. It's been great. And yeah. All
15. 0:37right, so the first thing we're going to
16. 0:39do is fix this block reaction thing. So
17. 0:44you see if we join the game and take out
18. 0:47our sword and we hit the D. You notice
19. 0:50that the animations kind of bug and of
20. 0:53course we get an
21. 0:54error. So similarly, the reason this
22. 0:57happened is because the animations
23. 0:59aren't loaded in yet, which is why we
24. 1:02made the hit reactions a part of the
25. 1:04characters
26. 1:05animations. So we can also just do it
27. 1:07for that. So we can go over here
28. 1:10to our blocked script and we can look
29. 1:13for the blockstroke. So we go to
30. 1:15block.reactions blah blah blah right
31. 1:17here. So in here we can add something
32. 1:20called uh block
33. 1:22reactions and then we can add in the
34. 1:25folders. So fist
35. 1:27uh dagger and sword like
36. 1:32so. Now we can just go ahead and drag
37. 1:34all these
38. 1:35here. So this is for dagger. So we can
39. 1:38now go ahead and remove
40. 1:40this actions folder and do the same
41. 1:42thing for fist and our sword.
42. 1:50And then let's go this for
43. 1:53sword. And this should be good now. So
44. 1:56since we changed the location of our um
45. 2:00block reactions, we need to change in
46. 2:02the script too. So we can go over here
47. 2:04and go to call this character.block
48. 2:07block reactions dot whatever our weapon
49. 2:11used
50. 2:12is dot dot dot and then two string the
51. 2:16random stroke like so. And now if we
52. 2:20play the game the animation should be
53. 2:21fixed. So we go over here equip our
54. 2:24sword. Oops. Let's see. Character
55. 2:29dot character dot block
56. 2:33reactions dot weapon used
57. 2:37And then oh right here. So we have to do
58. 2:40two string shrug one. So it corresponds
59. 2:43to
60. 2:44this. And then if we play the game we
61. 2:47should be
62. 2:52good. As you can see the animation's
63. 2:54load now. All right. So now that that is
64. 2:58done. I'm just going to go over all the
65. 3:00scripts
66. 3:01again. So basically just everything from
67. 3:04episode one to now.
68. 3:07So, first off, I'm going to go over how
69. 3:08we organize the workspace. So, let me go
70. 3:11ahead and move all of these to um the
71. 3:14map
72. 3:15folder. So, typically in games, we
73. 3:17usually like to organize them in
74. 3:19folders. So, we want to prevent any
75. 3:21unnecessary extra hanging parts in the
76. 3:24workspace in
77. 3:26general. So, I made a world a world
78. 3:28folder and then I also added effects,
79. 3:31hitboxes, live, which are just the
80. 3:33characters or the players in the game.
81. 3:35and map which contains everything having
82. 3:38to do with the
83. 3:39map. And now if we go to replicated
84. 3:43storage, we also have folders in here.
85. 3:46So we have remote events which handle
86. 3:47our replicating our VFX, blocking and
87. 3:51attacking. We have modules. So our state
88. 3:55service which we condensed it into three
89. 3:58different functions our check state
90. 4:01remove state and add state which
91. 4:03previously in a previous video we had it
92. 4:06in our systems folder but since we moved
93. 4:09it to replicated storage it's accessible
94. 4:11from both the client and the server now.
95. 4:14So that's good. And we have weapon data
96. 4:16just to obviously get what type of
97. 4:19damage we want things like that.
98. 4:22And let's move over to our service group
99. 4:25service which contains pretty much the
100. 4:27bulk of the combat
101. 4:29system. So we have um let's go over
102. 4:32let's go over the simple things first.
103. 4:33Our collision handler which just handles
104. 4:36the part where we collide with the
105. 4:38dummies. So you see that you are able to
106. 4:41not collide with the dummies which
107. 4:44mentioned in a previous video is for
108. 4:46things like getting flung if you dash
109. 4:48into something hard enough. So just go
110. 4:50through the
111. 4:51dummy and yeah so how we did that is we
112. 4:54use collision groups. So brief over
113. 4:57collision groups again if we go to model
114. 4:59and collision groups you'll see the we
115. 5:02set the collision groups of everything
116. 5:04to players. Well everything as in the
117. 5:06character and the dummies. So notice
118. 5:08that the characters or the players can't
119. 5:10collide with each other which this is
120. 5:12checked off like
121. 5:14so. And now if we go to our tool
122. 5:17handler, this just handles this. So if
123. 5:20we play the game and we equipped uh our
124. 5:24baton and dagger, this handles the part
125. 5:27where we just want to remove any related
126. 5:29items to the um the weapon once we clear
127. 5:34them all, which you see that all the
128. 5:35items get
129. 5:36removed. So that's that. And we also
130. 5:39added extra checks and things. So, for
131. 5:41example, if an item gets added to the
132. 5:43backpack, we check for that. As well as
133. 5:46if an item's already there, then we also
134. 5:48check for
135. 5:50that. And next up, we go we're going to
136. 5:52go to our comment
137. 5:54system.
138. 5:55So, I I believe in episode 1.5, we
139. 5:59discussed the idea of caching, which is
140. 6:02just storing modules in a certain table
141. 6:06so we're able to call in them again. So
142. 6:08this is much better than doing require
143. 6:10script.parent no weapons dot or hit
144. 6:14types default every single time we want
145. 6:18to just
146. 6:19uh call
147. 6:21that sort of hit effect that we want the
148. 6:24character to be or we want the target to
149. 6:27be inflicted upon. So because of that
150. 6:30we'll just cache modules like so. And
151. 6:32then as you can see down here
152. 6:36we are going to attack which we
153. 6:39find the cache modules the tool name and
154. 6:42we
155. 6:44attack. And same thing with blocking as
156. 6:46well. And uh once again to note you can
157. 6:50collapse certain parts of the script
158. 6:52with arrows so you can better read and
159. 6:55understand where everything is.
160. 6:59And over here in character added, this
161. 7:01is essential because we're essentially
162. 7:02loading the animations of the character.
163. 7:05So when we load them, this allows for
164. 7:07our, let's say, our blocked effect that
165. 7:10we fixed earlier to play because we're
166. 7:12loading the character animations which
167. 7:14contain the block reactions, hit
168. 7:15reactions, and
169. 7:18block. And now if we go over to
170. 7:21our weapons, let's go sword for example.
171. 7:26And you'll see that okay, we have a
172. 7:28function called weapon to attack. And
173. 7:30this just allows the player to
174. 7:33attack like so. So, let me just go
175. 7:36through a brief overview of the script
176. 7:38in general. So, obviously, if we want to
177. 7:41attack, we need to make sure the
178. 7:42character is
179. 7:44not having a condition to where they
180. 7:47can't attack. So, we use state service
181. 7:49for that. And we're checking if the
182. 7:50character is attacking, blocking,
183. 7:51stunned, or they're just not able to
184. 7:53punch. Then we just return end which
185. 7:56just stops script prevents it from
186. 7:58attacking. And another standard check we
187. 8:01have is if tool name let's say the tool
188. 8:03name is equal to sword. If sword is not
189. 8:06equal to this uh the script's name then
190. 8:08we return end. And we also want to find
191. 8:11the configuration folder for the
192. 8:13tool which is
193. 8:16this. And over here, we're just adding
194. 8:19in our or we're cycling through our
195. 8:23swings and we're playing our
196. 8:27animations. And down here, we're using
197. 8:29the client effects remote event to play
198. 8:32sounds. And right here is just our whole
199. 8:35hitbox event. And you'll see that we're
200. 8:38we're using the cached modules that we
201. 8:40cached earlier up here in the script and
202. 8:44calling upon them again to work on our
203. 8:46hit types which block
204. 8:48break and
205. 8:50default. And yeah, so essentially the
206. 8:54weapon types are the same across the
207. 8:55board. Of course, if you want to edit
208. 8:57anything, you can just go in here and
209. 8:59like play around with the animation
210. 9:00length, things like that. And
211. 9:03yeah, so let's go ahead and move on to
212. 9:06our hit types, which we have three basic
213. 9:09ones. We have default and blocked and
214. 9:13block break, which default is handles
215. 9:15when the player hits the player normally
216. 9:17if they're not blocking or anything like
217. 9:19that. Uh blocked obviously for when the
218. 9:23target is blocking and block break when
219. 9:26the target is being block broken.
220. 9:30And now we're going to go ahead and move
221. 9:32on to
222. 9:34our server script or our um our input
223. 9:40script. So if we open the input
224. 9:43script, you'll see that this is pretty
225. 9:46much uh the bulk of the client side of
226. 9:49the combat. Hence why it's around 400ish
227. 9:52lines. But here you see our
228. 9:54conditionals. We have can sprint, can
229. 9:56dash, can
230. 9:57block, and our is moving function.
231. 10:01And toggle trails is for this. When we
232. 10:04play the game and we start dashing or
233. 10:06sprinting, you'll see that the trail
234. 10:08gets toggled on and we start
235. 10:10attacking the trail gets changed to red
236. 10:13for our attacking trail. Oh yeah, and
237. 10:16another thing we want to note is you
238. 10:18notice that the hit box is still um
239. 10:21appearing. So way to remove that is you
240. 10:23can just go over here
241. 10:26to our weapon script. Let's say we want
242. 10:29to disable the or make the hitbox for
243. 10:31the fist transparent. We can just go
244. 10:34right here and just say hitbox clone
245. 10:35transparency is equal to one. And that's
246. 10:38going to make the transparency for the
247. 10:40fist hitbox set to one or invisible. So
248. 10:44if we equipped our fist, you notice that
249. 10:46we don't have a hit box anymore because
250. 10:47we made it
251. 10:51invisible. All right, moving on. We're
252. 10:54moving back to the script. All right,
253. 10:55toggle trails function. We went through
254. 10:57that and we have our change idle
255. 11:00animation, change run
256. 11:02animation, which just goes ahead and
257. 11:05changes our idle and run animation based
258. 11:06on weapon we have equipped and get dash
259. 11:09direction should be
260. 11:12self-explanatory stopping our
261. 11:15animations. And this is our dash
262. 11:17function where we play our animation
263. 11:20from our animations module which is
264. 11:22right here.
265. 11:25and we put the sound as well as doing
266. 11:29dashing
267. 11:30effects. This is where we do our body
268. 11:33velocity where the player actually moves
269. 11:35from the
270. 11:37dashing. And let's
271. 11:39see. All right. So, state handler. This
272. 11:42is how we put we wrap this all in a
273. 11:45render step method which just updates
274. 11:49our speed constantly based on what
275. 11:51statuses we have. And to reiterate from
276. 11:53a previous video, there's a priority
277. 11:56system to Roblox, which once again, if
278. 11:58you recall, Roblox reads things from top
279. 12:00to bottom. So, if we were to move the
280. 12:04sprinting status down here, the
281. 12:06sprinting status will override any of
282. 12:08the things that we already set up here.
283. 12:11So, it's important to understand
284. 12:14uh the priority of each of the statuses.
285. 12:17So, obviously, stun has a really high
286. 12:19priority, so it's going to be at the
287. 12:20bottom.
288. 12:23And as well as in the state handler in
289. 12:26the render step, we are constantly
290. 12:27updating the
291. 12:29animations. And down here, we're just
292. 12:32toggling our attacking and sprinting
293. 12:34trails. And now here is our mobile
294. 12:37support, which if touch enabled, which
295. 12:40is if you're on mobile, we're not going
296. 12:42to do anything for now. But if you are
297. 12:45on um console, then if you're holding
298. 12:49button X, you're going to be able to
299. 12:51attack. Otherwise, it's a normal input.
300. 12:53If you're on PC, you hold down your left
301. 12:55mouse button and you
302. 12:57attack. And as for sprinting, we made it
303. 12:59to where if you're on PC, you have left
304. 13:02shift. And if you're either on mobile or
305. 13:05console, you're just going to
306. 13:06automatically be able to
307. 13:08sprint. And blocking. This is our
308. 13:11blocking all the way here. Which
309. 13:15similarly to attacking, if you're on
310. 13:17mobile, the mobile block and attacking
311. 13:19functions are already handled in our
312. 13:22controller script right here. But if
313. 13:25you're on console, then blocking is
314. 13:27button B. And normally on PC, it's just
315. 13:32F. And then now finally, let's move on
316. 13:35to what we did previously, which is our
317. 13:37controller and mobile compatibility.
318. 13:41which uh render stepped. So, we want to
319. 13:44constantly update the visibility of
320. 13:46either the console or mobile frames
321. 13:49based on what device you're on. And
322. 13:52right here is where we start doing our
323. 13:55mobile attacking, blocking, and things
324. 13:58of that
325. 13:59nature. And yeah, that's pretty much it.
326. 14:03The other thing, well the last thing
327. 14:04that we did was client effects which we
328. 14:06cached all
329. 14:07effects and we
330. 14:11um we called on the cache modules in the
331. 14:14on client event method for the clan
332. 14:18effects. So all in all that's pretty
333. 14:21much the end of the series. Um I'm going
334. 14:24to hop in game and just show you the
335. 14:25comment once again. So, a brief shortcut
336. 14:29is alt P is for publishing the
337. 14:33game. All right, now that I am in game,
338. 14:36this is I'm just going to showcase the
339. 14:37combo one last time. Let me turn up my
340. 14:40volume and equip the sword, dagger, and
341. 14:43fist. So, you notice that when we start
342. 14:45running, our trails start playing. And
343. 14:49if we unequipped and equipped, you see
344. 14:51that trails start playing based on what
345. 14:53weapon we have equipped.
346. 14:56Yes, if we dash, you have some
347. 14:58effects. And now let's hit a
348. 15:02dummy. And let's set the effects to
349. 15:04work. And let's equip our fist, which if
350. 15:06you recall, we disabled the hit box for
351. 15:10that. You see, it
352. 15:17works. If we go ahead and clear the
353. 15:19weapons, you notice all the weapons
354. 15:21disappear.
355. 15:23And let's test out the bucking
356. 15:27dummy. And you'll see that the effects
357. 15:30work, any
358. 15:33rebu. And
359. 15:35yeah, and please leave me any
360. 15:39suggestions for any series or new
361. 15:42content that you want that y'all want me
362. 15:43to post, cuz right now I'm pretty drawn
363. 15:47on what type of series I want to do for
364. 15:49y'all. And yeah, put it in the comment
365. 15:51section.
366. 15:53So that wraps up the end of this long,
367. 15:57not not really long, but sort of a 9 10
368. 16:00episode series for
369. 16:02uh a basic comment system that you can
370. 16:04use in a lot of your games. So yeah,
371. 16:07thank you for watching and once again,
372. 16:09I'm going to open source this once I hit
373. 16:11600 subs. So please leave a like,
374. 16:14comment, and subscribe and thank you for
375. 16:17watching.
