Hi,
I'm using MotionStreaks for an animation, is only a line but in the simulator the line show alpha at end and looks great, but in the iPhone no, is only the line.
Some ideas?
Thanks.
Sorry my bad english.

MotionStreaks diference between Simulator and iPhone

ModeratorJuan, your English is good. Yeah, the simulator and the iPhone have different graphic chips and some OpenGL drawing (especially with lines it seems) is different. I havent used MotionStreaks, so I cant comment on that. But its a function of the hardware - you arent doing something wrong.

I wrote motion streak so I might be able to answer your question. Last I checked the results were the same on both the simulator and the iphone (1st gen), but I haven't used it in a bit so things might have changed. Motion Streak constructs a polygonal ribbon behind your target object, so it doesn't use lines for drawing. It should fade the trailing edge of the streak out as it emits.
Can you provide more details of whats wrong, a screenshot or the code your using to initialize the streak?

MemberHere is mi code
streak = [MotionStreak streakWithFade:1.1 minSeg:2 image:@"streak.png" width:6 length:5 color:0xFFFFFF];
[self addChild:streak];
[self schedule:@selector(onUpdate:)];
I have a linePoint Sprite and I play an action, then onUpdate i do
-(void)onUpdate:(ccTime)delta {
[streak setPosition:ccp(linePoint.position.x, linePoint.position.y+3)];
}

One thing that could be different is that your .png has alpha premultiplied on the device, but not on the simulator.
try converting your .png image to .gif

This is my first post :)
I successfully got the motionStreak to work on the iphone4 and the simulator but it doesn't seem to work for the iphone 3g. I tried changing the .png format to .gif but it still doesn't work on the iphone 3g. Is the iphone 3g not compatible with motionStreak? Thanks in advance.
