@aaronventure this did the trick ! many thanks!
//button
const var Buttonx = Content.getComponent("Buttonx");
inline function onButtonxControl(component, value)
{
if (value)
{
// Button pressed, start animation
p.startTimer(1000.0 / object.frameRate);
}
else
{
// Button released, stop the animation
p.stopTimer();
}
}
Content.getComponent("Buttonx").setControlCallback(onButtonxControl);
