Tells the physics engine that this object is a bullet.



返回: 布尔值


This variable defines whether or not the instance is extremely fast moving (for example a bullet). The default value is false but if set to true this tells GameMaker Studio 2 that the instance will be moving at such high speeds that it will require more expensive collision detection to ensure it doesn't pass through other instances undetected.


with (instance_create_layer(x, y, "Bullets", obj_Shoot))
   phy_bullet = true;
   physics_apply_local_impulse(0, 10, 0, 200);

The above code creates a new instance and then defines it as being a "bullet" in the physics world before giving it a massive impulse along the y axis.
