Multitouch

robert.mccarthy

Hello All,

I was wondering if there was a tutorial on multi-touch to move and 'rotate' an actor?

I know how to get multi-touch working for two seperate actors, but need to know how to get it to work out how it will rotate an actor when I select it.

Thanks,

Big Dog Studios

make two attributes spinX and spinY
create an invisible actor with rule:

when touch is pressed,
Constrain self.positionY to touchY,
Constrain self.positionX to touchX,

Constrain game.spinY to self.positionY,
Constrain game.spinX to self.positionX,

Spinning:

When touch is pressed and inside
constrain self.rotation to VectorToAngle(self.positionX-game.spinX, self.position.Y-game.spinY)

Hope this helps....
