Setup:

1. Unzip the .zip file and import the .yymps file into your project. (Tools > Import Local Package)

2. In the create event of your player character, run 'movement_initiate();' You can change all of the variables at any time, in this example the default variables are changed. (You can find a list of all the variables below)

3. In the step event of your player, run 'movement_update();' (You could also update the variables here, for example, if you had a booster you could change the speed when colliding with the booster)

4. Create an object named 'obj_collider' and add all the objects that you want to be collidable as its children

Variables:

Default variables are for a 32x32 player, you may need to change the variables depending on the scale/resolution of your game
