[@foolspark]

I'm only a couple of episodes into this series and this is honestly amazing. I've seen so many roblox scripting tutorial youtubers try and do game development series like these, but never manage to execute it as well as you do. You go really into depth and explain thoroughly whenever you try to teach something, instead of just giving us the code, and telling us to copy it down.

i thought you were making a tower defence not a paintball :D jk, really appritiate this tutorial, im not even making a towr defence, i watched this on random and it really helped me with my game, thnaks

[@theofficialjorden226]

Will you do things like a shop, unlocking towers with levels, tower upgrades, and animations, certain places where towers can be placed, or enemies attacking towers and cool stuff like that, or some of the basic stuff like things from Bloons TD? Either way, it's helping people who don't know much about scripting create a tower defense game

[@calengo454]

That's the problem. IMO people who are new to scripting should start with much simpler projects in which don't make you just copy scripts, like 89% are doing. I wish every person in the comments would know that you won't learn or make a good game if you ALWAYS use other's stuff and pollute the comment section with "Hi WiLl yOu mAkE a flYIng rObOT That SHooTs Cars?? Btw I'M haVinG proBLEms with The ScRipT i litEraLLy juSt CopIeD fRom YOu!!!1 whIch meAns tHe TuToRIAl wON't WoRK and it'S YOuR faULt!!!!1 "

[@lambarini]

@@calengo454 true but at the same time no. I learned ALOT from tutorials and now I can code stuff but nothing crazy. The problem with people is that they just copy and don't look into it.

[@calengo454]

@@lambarini yes, that's what i meant. i was referring to people that always ask for others to make stuff for you, without even trying anything. i had a friend like this and thankfully i didn't make anything for him. i also learned from "how to make a game" tutorials but their comment sections are filled with people that think scripting is just copying from a tutorial, which almost always end up in them saying "tutorial doesn't work". sure copying some stuff is ok who doesn't do it but it's like you said, they don't look into it and have absolutely no idea what they're doing my biggest problem with doing gigantic projects is that i tried to make one when i didn't know anything and i almost gave up forever, and i don't really want that to happen to other people... it sucks

[@theofficialjorden226]

@Bocho no, I know how to script and I'm not making a tower defense I'm making a platformer game

[@theofficialjorden226]

the game is being solo developed by me. It's hard, but everything is coming along great. the platformer mechanics let you do acrobatics like Mario and you can gain momentum by going down slopes and stuff like a sonic game. I also made the music soundtrack sound something like Sonic Adventure 2 and Sonic Mania. The game was supposed to be released this year but got delayed until next year because of Roblox being down and some school stuff.

[@sebobebo10]

This series is actually really helpful, I do have one question about line of sight. So basically, if there was a tower placed in the middle of the map and there was terrain between the tower and the enemy, the tower cannot shoot the enemy. So how would that be scripted

[@GnomeCode]

You could use raycasting for that if you wanted, though I don't think many games use line of sight for there towers. After all, it's more of an 'arcade' type game

For now you can attach a transparent cylinder part at the bottom center of your tower and change the size of it to whatever your maxDistance is times 2. If your maxDistance is 50, then the size of the cylinder should be 100x100.
