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.

[@gggamingtakeshi7035]

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.

[@faded_ace5144]

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

[@KodaBunn]

this is so incredibly underrated

[@Xisco72]

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

hey, I'm working on a throwable football and I want the nose of the football to be looking at the direction that the player throws in. I have my own custom caster which handles the football drop and physics.

CFrame.LookAt()

[@qxxrd]

@@pepperdayjackpac4521 Can you please elaborate more?

[@pepperdayjackpac4521]

@@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.

[@qxxrd]

@@pepperdayjackpac4521 I have tried to do what you said but the problem now is the when the player throws to the side the nose of the football is fowards and not facing where the player aimed to. Caster Code: NewProjectile = self.Projectile:Clone() DirectionVector = (target - origin).Unit PositionVector = *Trajectory Calculations* -- THIS PART IS IN A LOOP NewProjectile.CFrame = CFrame.lookAt(ProjectilePosition, DirectionVector)

Try rotating it by 90 degrees in the code, also if you right click the part and click "Show Orientation Indicator" it's going to show you where the front side is

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?

you need a folder for the projectiles you are shooting at.

[@citizenfoffie7605]

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

how do i make it so when it touches a part it destroys and doesnt just go through it

End the loop whenever the raycast detects something

Hey, is it possible to use this on a model? I have a firework game and I want to move the firework physics to client side but every time I tried I couldn’t get it to work.

Could you be more specific? Maybe you could even open a devforum post about it

Yeah absoloutely. Fire the event, whenever you want the firework to be activated. Just name the start, dest and force. It should work.

[@haxking2]

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]

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

[@thetable8175]

if you wanna do stuff with runservice I'd put checks with like ticks() to make sure your code acts as desired

Since ray result is nil, your visualization will not follow anything since it does not exist so do Part.Position = projPos
