	Type	Desc
motion_set(direction, speed)	function	sets speed and direction variables of an instance in one line
instance_place(x, y, object)	function	exactly like place_meeting except this function returns the 'specific instance identifier' which means we can do stuff with the instance we have collided with.
point_direction(originX, originY, targetX, targetY)	function	returns the direction from one point (x1,y1) to another point (x2, y2). Helpful for setting course for a specific direction. We will use it in this example for a 'controlled bounce' (as opposed to a 'natural bounce').

sprBall
sprBrick
sprPaddle
sprTargetBlock

Set the mask and origin of ball for spot on bouncing:

Next, set the origin of paddle for controlled bouncing a short distance below the middle-centre of the paddle surface:

The reason for this is explained in this diagram:

objBall Create event:

randomize();
motion_set(irandom_range(225,305),7)

objBall Step event:

if place_meeting(x + hspeed, y + vspeed, all){
  //after we bounce, if there is a target block,
  //we will have to remove the target block:
  targetBlock = instance_place(x + hspeed, y + vspeed, objTargetBlock);
  //for the paddle (only)...:
  if place_meeting(x + hspeed, y + vspeed, objPaddle){
	//...give the user some control as to where they are aiming,
	//which means an 'unnatural' bounce:
	direction = point_direction(objPaddle.x, objPaddle.y, x, y)
  }
  else{
	//...otherwise use a regular (natural) bounce:
	move_bounce_all(true);
  }
  if (targetBlock != noone) {    
	with (targetBlock) {
		instance_destroy();
	}
  }
}

objPaddle Step event:

switch (keyboard_key) {
   case vk_left: x = x - 7; break;
   case vk_right: x = x + 7; break;
}
