How to use a model as a projectile

[hot creek]

I've been trying to use a model as a projectile following the projectile physics video, but it only moves the primary part. I used weld constraints to weld the other parts to the primary part but the other parts don't follow the part.

I could help with this

But it depends on what kind of projectile it is

Id say try cframing the parts trajectory using the video as a reference,
then changing the math calculations with applied impulse next to the reference until its close to the same

Why would you need welds?

[hot creek]

because welds often hold parts together

and i thought it would work

[hot creek]

the main projectile is just a part

correction: using welds, the other parts go to where i want them to go but do not have the same starting position as the main projectile

Whats the game/application of the projectile? if ik the shape itd be better

[hot creek]

so im making a game about the player throwing bombs

i wanted to use the projectile physics video to script the throwing of the projectile

the projectile would start at the character's root part and end around the player's mouse position

i already created the input handling local script and the server script to create the bombs

the only issue is only the primary part of the model (the main projectile) is at the correct starting location (the root part) and the other parts are not

but they both go towards the mouse position correctly

you could try using fastcast

that realistically simulates bullet velocity and bullet drop and stuff using raycasts

but if you're looking for projectiles that just go from point a to point b then you could tween parts

raycast and then tween a part to the position where the raycast hit

Fast cast would probably be best. On devforum theres a link to a trial game which has similar application to what you want
