Example 1 with GameLoop

use of de.gurkenlabs.litiengine.GameLoop in project litiengine by gurkenlabs.

the class PhysicsTests method testBasicCollisionDetection.

@Test
public void testBasicCollisionDetection() {
    try (GameLoop loop = new GameLoop(30)) {
        Creature ent = new Creature();
        ent.setSize(16, 16);

        ent.setCollisionBoxHeight(16);
        ent.setLocation(10, 10);
        IPhysicsEngine engine = new PhysicsEngine();
        engine.add(ent);
        loop.start();
