Pathfinding #1 - Một đường thẳng [Game Maker Studio 2 | Cơ bản]

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 linear functions you can find under motion planning in the GameMaker manual. By using mp_linear_step, mp_linear_step_object, mp_linear_path or mp_linear_path_object in the step event the instance in question tries to get to the target point assigned. And that is pretty much it. If a direct path isn't possible (because some instances are flagged as solid and you set checkall as true) it will get stuck if it collides.

In part Pathfinding #2 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.
