The double radius ball is in fact what is called the Minkowski addition, in this case of two circles. It's a technique often used to calculate and resolve complex collisions, because it turns the collision between two bodies into the collision between a point and a body. The point turns into a line...

Do you think the way I did is going to work? Like im not getting the normal from the ball itself, im getting from a invisible ball that has the double radius of the red ball. Knorke's point that Box2D might cause things to behave in a way that differs from your vector prediction is important. Some ...

Thanks everyone, I will try to apply this, hope I get it, I have zero experience calculating vetors

... To find the reflected vector, you flip the direction of the incoming vector, project it onto the normal, then get the rejection (the difference between the flipped incoming vector and its projection onto the normal) and add that rejection twice to the flipped incoming vector. This will place yo...

If you don't want to do any of the math, then you can just simulate the shot. Take the table, the cue stick and the balls into an separate physics environment, do the shot there and if the white ball hits any other ball, then you have all the information you need to draw what you want: At the momen...

See if you can work with ChatGPT for it to explain vector reflection for you. You have the incoming vector and it's being reflected on the normal of a surface (like the surface of a ball, or the surface of the boundaries of the table). To find the reflected vector, you flip the direction of the inc...

My goal is to do something like this: https://imgur.com/a/o4HaceP This is what a got so far(just the line stopping to draw when detect a ball): https://imgur.com/a/rm8rStf I'm using physics module in balls and table. I don't have idea how to do it, could someone help me? update1: https://imgur.com/a...

Make .love not .rar

sorry about that, its my first time making a game.

Thanks all, that helped me a lot!
