Create a simple game where the player can move the character around, within a certain bondary. This game also includes collectible items that the player must collect to win the game. The bonus part includes animations, and enemies that can kill the character by touching it. The map is provided in a separate .ber file. For detailed information about the project refer to "subject.pdf".

Despite the project being quite lengthy compared to others, it was rather a pleasant coding experience. The most complex part about this project was creating a basic physics model that allows the character to jump and collide with the elements around it, I wanted to do some realistic force-based physics but ended up using a only-velocity physics model, no mass, with fixed starting velocities and gravity, mostly because I felt that the former was beyond the scope of the project (and it was quite a pain lol). The hitbox is not 100% precise, it triggers the events a little bit before real collision but it's negligible.
The linux mlx has a buggy feature where the transparency of the .xpm isn't handled properly so it shows a black pixel instead of a transparent one, I believe this has been fixed but I couldn't find the fix anywhere, that's why I've changed the color value of the pixels to make the black background around the sprites and textures 'disappear'. In a non-buggy version of the mlx the color value of the background pixels should be changed to "None" again in every .xpm file.
I've included a small linux program that draws a [n x m] empty map if you wish to test it with different sizes (the background may be weird if sizes are too big due to the library not resizing backround images).

Here is a rough preview of the game with the buggy mlx library
