Part 2 is out now!!! Learn how to make your projectiles bounce!! kzread.info/dash/bejne/qqdqqZSEmNPPgJc.htmlsi=ju6EgeyIsvYbWpXu

very useful, im testing ideas on developing a matchlock gun system, a single tool instead of getting over my head with an entire game, helps great since the accurate physics of it performs way further from hitscan than other weaponry

Fantastic video, exactly what I needed and you actually managed to explain it pretty well

you're talented oml❤

Thanks for the tutorial, so helpful :D

This is definitely complex but what's more complex are the emotions you feel whilst trying to deal with body velocities and watching something move in the air at a total speed of 5fps. So ty

This is gonna be so good for my fighting game knockback, thanks

Thank you very much, I learned a lot from this video.

this is so incredibly underrated

you resumed my physics semester

THE WAY I CLAPPED AND SAID YESSS! 💀 WHEN YOU SAID I'M GONNA TEACH YOU HOW TO WRITE IT YOURSELF. So many dang tutorials are just people showing us how to use the modules and I've always hated those videos because I want to know how to do it not just rely on someone else and never learn. I was about to click off and then you said "the module FastCast" I'm so happy this wasn't one of those.

Thought I was learning physics. Anyways, nice video

thx for the video

Here I am, with my non mathematician brain making a goal part created on mouse position with a limited range, then moving it downwards and slowly accelerates downwards faster simulating gravity and having my raycast slowly approach it based on bullet speed when I could've just done this.

I was looking for client-side hitbox as it fixes network latency issues but nice tutorial.

Hey awesome video! When I put in a model as projectile it moves just fine but it looks a little bit choppy because I am just settings its position every RayCast do you think Tween or Lerping would work in anyway for the projectile so it looks smove when it moves?

The issue with having hitboxes client side is that a user can exploit them to hit every time. I prefer having them on the server for that reason, also because everyone gets the same performance that way, one persons hitbox accuracy is the same as anothers.

Yeah. The client can tell the server where to start it, but all validation should be on the server only. As long as simulation is consistent between client and server the client predicted simulation should be almost the same as the server, if ping is high there may be issues though. But it'll still feel good to use as long as it's predicted on the client rather than appearing 0.2-0.4s in the past on your client.

I haven't seen anyone else with this problem in the comments but every time I require the module it says attempt to call a table value.

Would there be a way for me to set it to hit a certain amount of studs by adding on angle(but without moving the mouse up), to create a zeroing effect

only reason i subbed is to fix the 666 nice video btw

Can i use this to make a cannon like bofors or flak 88 ?

I don't think this is the best for big projectiles, because i'm using this to move a trash MeshPart, and sometimes it goes through parts that shouldn't because they can collide. For example, i'm throwing this meshpart against a house wall, it collides with it and detects the hit, but it trespasses it. Maybe because the mesh is kinda "big" and since you are constantly changing the position, it goes through them unlike when you are using a velocity mover

@@qxxrd CFrame.LookAt will angle your obj so that it faces its targetPosition. It takes in two parameters: the starting position (the position of the obj) and the targetPosition (which is where the obj will be facing towards), both are Vector3. if your football is changing directions, then you need to recalculate the starting and target position each time so that the nose points like it would in real life. But if it's just moving in a straight line, then you won't need to recalculate.

A trick, instead of using Heartbeat and wait() in your script, use task.wait(). The task.wait() command can run at the same speed as heartbeat (60hz, every frame), but you can also input seconds into the parenthesis the same as normal wait().

great video, idk why but I've always been under the impression that this would've been more complex. quick question though, does using runservice to execute code every frame on client (even if it's just changing a few values) not a good practice?

@Antonio-vf2xj

Well i didnt see the video fully but yea, if ya uses renderstepped, but as its used on clientside i guess, it doesnt affect server at all, so maybe slighty lag but no server lag so like data saving and everything else is safe

@thetable8175

9 ай бұрын

as far as I know you need to take into account people having different frame rates causing codes to run too fast or too slow, I've seen many games put for example dashes that update a BodyVelocity's direction every frame for a set amount of times and then destroy it causing higher fps to destroy the BodyVelocity earlier making you travel shorter while capping your fps at around 30 would make it go a lot further
