Physics Service not working right

I am making a Ball, which your player stands on. The ball can jump, but it seems to not work right, so I put both the ball and its other parts and the player and its other parts into a collision group, however it has not changed anything. How would I fix this?

i dont think that should be in “scripting support” but can you explain your problem clearly? Is your ball not bouncing like a “Ball” ? if so i think you should change “elasticity” property under “custom physical properties”

so uh turns out I figured out the issue; I was trying to give the ball the collision ID 14, but it didnt work. so I made a new one with a string instead and gave the ball the correct ID, thanks for the attempted assistance tho
