Face the Mouse

Pro

You can make an object's sprite face (look at or point at) the mouse by changing the object's image_angle^[pro] variable using point_direction().

This technique can be used to make a turret or other enemy face the mouse automatically.

// in step event
image_angle = point_direction(x,y,mouse_x,mouse_y);

This will only make the sprite face the mouse, it will not set the direction of the object to move towards the mouse. For this you should set the direction first and the image_angle second.

// in step event
direction = point_direction(x,y,mouse_x,mouse_y);
image_angle = direction;

Note that the object will not move if speed is set to 0.

Shoot Using the Mouse

There are two ways to "shoot" using the mouse. Which one you use will depend on the type of game you are making.

Shoot at the Mouse Cursor (2D Mouse Aiming)

To shoot at the mouse cursor

1. Set the speed to the speed of the fired bullet.
2. Set the direction of the bullet using point_direction(obj_bullet.x,obj_bullet.y,mouse_x,mouse_y);

Shoot With the Mouse (Mousehairs)

You can also shoot by using the mouse as gun sights to simulate light gun games. ^{[info needed].}
