Collision detection made more simple?

Question

When I try to program collision detection in games, I always end up doing it in quite a cumbersome way. Consider the following code:
//Up
} else if(mouseX > 60
&& mouseX < 100
&& mouseY > 360
&& mouseY < 400
&& this.y > wall.y + wall.h
|| mouseX > 60
&& mouseX < 100
&& mouseY > 360
&& mouseY < 400
&& this.y < wall.y
|| mouseX > 60
&& mouseX < 100
&& mouseY > 360
&& mouseY < 400
&& this.x < wall.x - 20
|| mouseX > 60
&& mouseX < 100
&& mouseY > 360
&& mouseY < 400
&& this.x > wall.x + wall.w) {
this.y -= 5;
That is my code for making sure my player doesn’t move through a wall object when pressing the up key(!). This I have to repeat for every key (oh gawd). There’s got to be a simpler, less verbose way to do this, right?

Answer 1

Truls Nilsen Hey, your collision detection is not good :p
Check for basic aabb collision detection :)

Answer 2

Truls Nilsen sorry, ofc aabb is not suitable here :)

Due to no connection error i have to post there one of my game that uses collision detection you might be interrested in :)

Function is on line 1178 - 1219.
Actual checking and calling the function is on line 262 - 291.

Answer 3

I see your point, however I’m trying to stop the «player» from moving through objects, meaning that there has to be separate cases for each direction, right?
If I do AABB basic, then i can execute some code if there’s an intersection. But there’s 4 different types of intersections here, based on which direction the player moves in.

Answer 4

So it is like an abstract function, (since it returns true) and then you just implement it elsewhere? Interesting.

Answer 5

I finally figured it out! Please check out my code web p5 js to see how i implemented it. Also, let me know if it could have been done easier
