In the main program I randomly choose an object which I'd like to animate, so I call the function with the object as the argument. The first loop is okay, x
is finely set, but in the next turn it becomes undefined
.
Something like this:
var anim = {
mainFunc: function(x) {
anim.update(x);
anim.redraw(x);
window.requestAnimationFrame(anim.mainFunc);
},
update: function(x) {
},
redraw: function(x) {
}
};
var n=Math.floor(Math.random() * (ArrayOfAnimObject.length));
anim.mainFunc(ArrayOfAnimObject[n]);
You either need to create a reference or wrap the function call in another function like so:
mainFunc: function(x) {
anim.update(x);
anim.redraw(x);
window.requestAnimationFrame(function() {
anim.mainFunc(x);
});
}
