Building a physics engine to get things moving
Create a new class called PhysicsEngine and edit it to match the following code:
class PhysicsEngine {
// This signature and much more will
//change later in the project
boolean update(long fps, ParticleSystem ps){
if(ps.mIsRunning){
ps.update(fps);
}
return false;
}
// Collision detection method will go here
}
The PhysicsEngine class only has one method for now – update. By the end of the project, it will have another method for checking collisions. The signature of the update method receives the frames per second and a ParticleSystem instance. The code simply checks whether ParticleSystem...
