Button which keeps applying impulse

Hello.

I have an object which is affected by a Chipmunk/SpaceManager impulse. I'd like to be able to keep my finger down on the button and have the impulse keep triggering, instead of just triggering once.

So, I'm looking for a way to keep repeating the method, bu holding a button down. Any ideas? :-)

In your tick method, check if the button is selected. Then you can apply a impulse continuously. This only works when you use a CCMenuItem.

-(void)tick
{
if(myButton.isSelected) [self applyImpulseOnBody...];
}

Expanding on domp's suggestion, you can also schedule/unschedule a selector when the button is selected/deselected if you want to control the rate of impulse.

Hello.

So, the button should call a timer which then fires the impulse, if the button is still held? That seems sensible, cheers :)
