This is the second in a short series of remaking the battle system which you see in Undertale in GameMaker.

What is Undertale?
Undertale is a video game made also in GameMaker by Toby Fox where
you play as a child that is being trapped in an unknown world and your job in this linear story is to progress. The difference is that you can genocide monsters, be neutral or even befriend them. This throws the concept of enemies being simply neutral farm on it's head.

// Part 2
This time we have to remedy that we want the player heart to be trapped inside the action box. For that we use the action box's bounding box points (x,y of each collision rectangle point) and put there 2 horizontal walls and 2 vertical walls. These walls we do stretch with the box's sprite_width and the box' sprite_height. This method allows us to update the walls x,y values as well their stretching so that they adapt to the action box during run time. That is it!

🚧 For the future: This series is under construction. There will is a free downloadable project file for everybody, so you can grab and do whatever you like to do with it (you can credit me, but not necessary). Also, this video series will be handled like my Hotline Miami series. If the views drop off a cliff (that I do see happening) it will be then discontinued.
