Collision detection made more simple?
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?

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

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.

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.

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

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
