Python Engine.add_system Examples

Example #1

    def test_system(self):
        Engine.reset_indices()
        s = TestIteratingSystem()
        e1 = Entity()
        vel = VelocityComponent(1, 0, 0)
        pos = PositionComponent()
        e1.add(vel)
        e1.add(pos)
        engine = Engine()
        engine.add_entity(e1)
        engine.add_system(s)

        for i in range(10):
            engine.update(0.5)

        self.assertEqual(pos.x, 5.0)

		e1.add(pos)
		engine = Engine()
		engine.add_entity(e1)
		engine.add_system(s)

		for i in range(10):
			engine.update(0.5)

		self.assertEqual(pos.x, 5.0)
