After some trial and error, I used this document's method for 2D collisions : https://www.vobarian.com/collisions/2dcollisions2.pdf(that OP linked to)I applied this within a JavaScript program using...

I would consider using a quadtree if you have a large number of balls. For deciding the direction of bounce, just use simple conservation of energy formulas based on the collision normal. Elasticity,...

I see it hinted here and there, but you could also do a faster calculation first, like, compare the bounding boxes for overlap, and THEN do a radius-based overlap if that first test passes. The...

Well, years ago I made the program like you presented here.There is one hidden problem (or many, depends on point of view): If the speed of the ball is toohigh, you can miss the collision.And also,...

One thing I see here to optimize.While I do agree that the balls hit when the distance is the sum of their radii one should never actually calculate this distance! Rather, calculate it's square and...

You have two easy ways to do this. Jay has covered the accurate way of checking from the center of the ball.The easier way is to use a rectangle bounding box, set the size of your box to be 80% the...

To detect whether two balls collide, just check whether the distance between their centers is less than two times the radius. To do a perfectly elastic collision between the balls, you only need to...

A good way of reducing the number of collision checks is to split the screen into different sections. You then only compare each ball to the balls in the same section.
