Need help with invert movement

patapple

hi,

i'm trying to create a small special power up in my game to . i have two actors:

PLATFORM:
-touch is pressed
self.position.x TO game.mouse.position.x

-touch is pressed AND game.invert IS true
self.position.x TO -(game.mouse.position.x)


POWER UP:
when collide with platform -> change attribute game.invert TO true

i want when the platform collide with the power up, that invert the movement ( if i drag left, the platform must go to the right!)

what is the problem?

Try change self position to (gamemouseposition-(gamemouseposition*2)

@gameARN it doesn't work. When the power up collide with platform, the platfrom dissapeares

Thats scary...

i found the problem: if i do -self.position.x when my actor is 400 it goes to -400 and i can't see it on the device. i need to put the symmetry mirror (can i say that in english?) at 320 (mid of the device display).

any idea on how to do that?

Interesting... *thinking

mmh i already tried it but there is always the symmetry mirror to 0. you can't position the actor in middle without have the finger out of the screen (this is impossible)

@patapple Ahh i didn't understand what you said.

it isn't impossible go to the white actor and change it to +480 isnstead of +240. Im sure it works now!
