Four-Way Gravitational Engine

[Darkcoucou]

In the last couple months I've been working on a project using "Fake Gravity Platformer Test with Shooting"
as a template.

The goal of my project is to create a Platformer with four-way gravity.

This is how the Code is supposed to work: First, it is decided which Code should be executed depending
on the current gravity, then every direction of Collision is represented by a Subroutine.

Each of those Subroutines follow the same scheme:
The Code tests if one pixel collides with the block and then tests for another one in the
same row/collumn (depending on which direction and which gravity)

This is supposed to create a glichless "Hitbox" for the player character.

This sadly doesn't work for a reason unknown to me
(The player can jump through walls or glitch his "head" halfway into a block supposed to be solid)

I've tried many methods to fix this issue:

-Make the Player Coords normal values instead of float, hoping it would help, but it didn't

-Tried different PlayerCoords-to-Block-Value conversions like
division, modulo and bitwise

-Change Order of Subroutines

I'm clueless and I've completely run out of ideas.

Does anyone know what the Problem could be?

 

I attatched the current state of my project:

And how I'd imagined the working subroutine to look like:

Sorry if this sounds unfriendy or something, this is my first post here...
