I am using spritebuilder to create the CCParticleSystem. I tested the smoke particle with gravity mode and speed of 0 and speedvar 50. The emitting angle is 0 degree. It is working great in the SpriteBuilder. However, when I run it in the Simulator and iphone 5, the position of the particle becomes so weird that, it tends to travel very fast to angle 0 instead of angle 180. It looks like the emitter is changing position, but when I NSLog it, the position is not changed. I have also tried changing the particlePositionType. It behaves the same way.
I also tested out the burning particle, the emitter position is also off by certain amount of the given position. This is not happenning before updating to XCode 6.3, so is there any compatible problem or something wrong with the XCode?
I would greatly appreciate any help
