hspeed

hspeed is one of the "built in" properties that all instances have and defines the horizontal movement speed (along the x-axis) of the instance in pixels per step. So, an hspeed of 3 means 3 pixels of movement to the right (+x) every step, and an hspeed of -3 would mean 3 pixels of movement to the left (-x) every step.

Note that if you set the speed and/or direction variables then the hspeed value will be updated automatically to reflect these changes, and likewise, changing the hspeed value will also affect the speed and direction values. Also note that gravity, gravity_direction and friction can all modify the value of this variable when they are used in your games.

Syntax:

hspeed;

Returns:

Real (single precision floating point value)

Example:

if (keyboard_check(vk_left)) hspeed = -5;
if (keyboard_check(vk_right)) hspeed = 5;

The above code will change the horizontal speed depending on which keys are pressed.
