Collision Callback not works at the moment created new fixture?

Jan 8, 2012 at 7:32 PM

Hello,

I found a problem while using callback function,

My character has a collision callback function to detect is the fixture collided a valid platform to stand,

and this function will not be called while I generate a new fixture on my character.

While I generate a new fixture at the character's position,

it just make a collision so my character will be pushed out of the new fixture.

Is there any way to solve this, make callback works at the frame that creating a new fixture?
