Make a ball roll

Questions & Answers
1

Hi, just a quickie, how can I make it so that my joystick adds force, rather than just moves an object? I think it is this that I need to fiddle with. I’ve been messing around with it to no luck for a while now :frowning:

(actual script)

 movement *= speed * ( ( absJoyPos.x > absJoyPos.y ) ? absJoyPos.x : absJoyPos.y )

Thanks all

New code added to help -

camerarelativecontrol.js (goes on char)

Joystick.js

Thanks in advance

Wonderful, wonderful helpers :slight_smile:

Your movement is done by a character controller at the moment => character.Move( movement );

your variable ‘movement’ is already Vector3 , so just replace at that point in the script (line 58 on your pastebin) with =>

//character.Move( movement );

rigidbody.AddForce ( movement );

:slight_smile: remember, the ball need a rigidbody component attached to it.

some info on rigidbody =>

hope this helps

Rigidbody.AddForce is what you want… but I can see in your script it’s there but has been commented-out, how come?

Completely untested but I guess something like this would work, although you might need to change the Force Mode.

rigidbody.AddForce(absJoyPos.x, absJoyPos.y, 0, ForceMode);

err…

can i suggest u to download a demo called “Rolling Ball” (i think) in UNITY ASSETS…

there’s a script where the ball moves without a character controller…

except it cannot jump… (yet)

its free… (at the moment…)

hope this helps u…
