This basics video tutorial shows you how to create a very simple "follow" a target Ai/pathfinding in one line of code for GameMaker Studio 2.

These potential functions you can find under motion planning in the GameMaker manual. By using mp_potential_step, mp_potential_step_object, mp_potential_path or mp_potential_path_object in the step event of the instance in question it tries to get to the target point assigned plus avoid solid instances/the instance to check. And that is pretty much it.

This method is very easy and powerful in levels that have no difficult terrain like rocks or tree where the potential function is good enough to guide the enemy instance around it. Mazes or more complex level structures will be a challenge to impossible to guide through.

In part Pathfinding #3 we will discuss a more versatile function the, mp_potential_step which can be used to avoid collision and actually go around instances blocking the path. This is of course a bit limited if you have maze like structures which require a bit more complex approaches. This will be solved in Pathfinding #3.
