Java programming to achieve a simple collision detection function example in the game

This article describes the simple collision detection function in Java programming. Share with you for your reference, as follows:

Today, I was writing a small game of tank war at home. I encountered a small problem of simple circle and circle collision detection,

The process of collision detection mainly includes the following three steps:

1. Collision detection: returns the Boolean judgment of whether two or more objects collide.

2. Collision determination: find the actual intersection position between objects.

3. Collision response: decide what action to take for the collision between two objects.

The following is a simple collision judgment process between two circles:

In short, when the actual distance between the two circles is less than the sum of the radius, it indicates a collision. At this time, modify the Boolean judgment flag.
