Accelerate towards mouse (please help)

StorerDev

I am having trouble with accelerating towards my mouse event. I have it set so when i press down on the mouse it accelrates towards it on a scrolling background, but for some reason it only JUST BARELY goes towards my mouse touch. i got everything right i think its at - game.mouse.position.x - game.mouse.position y, - for where it needs to accelrate towards....PLEASE HELP !!! this has been driving me crazy.

well im making iphone 4 graphics, so i have it set to a 960x640 screen so no i havent even tried it smaller yet

StorerDev

okay so i tried it with smaller graphics, but now everytime i get past the first set of 480 it just reverts back and doesnt let me go through my scrolling backround

As mentioned in The Unofficial GameSalad Textbook, you use scene attributes — by creating an instance of a prototype actor — to read the camera origin. That gets added to the mouse position. Save that data to an attribute... one for X and one for Y. It should work. I'm using this technique (and many others... ha ha!) for BOT and it works great.

Bot seems awesome man, but could you explain that a little more detailed? i want the camera to move with my actor and it does. its just once it starts scrolling it reverts back the original. it is also still having problems with just barely accelerating towards my x,y mouse coordinate.

In the accelerating actor you need to drag it in to the scene, double click on it, click on the big pad-lock, and then change your code to:

mouse.x+scene.camera.origin.X
and
mouse.y+scene.camera.origin.Y

Yeah i changed that and now my guy isn't moving at all....huh

Thanks you so much for bringing this up. This had been plaguing me for some time on a side project. I just figured scrolling & non-scrolling coordinates couldn't talk to each other. Makes me want to finally buy the 'Unoffical GameSalad Textbook" app too see what else I'm missing.
