2d collision with rotated pictures

[razerbladex43]

Hi everyone,
i have a big question. my problem is that i want make a collision system beetwen two rotated/angled sprites. theses sprites are both same sizes and they have rectangle form. I need it for the tank game i'm actually making and it's very urgent so i need your help.
thanks in advance.

Take a look at the HC library.

Rotated rectangles are not simple and it's even harder if you want to have some sort of decent collision response.
I recommend using love.physics or avoid rotation altogether.
For example, you can use circles or just rotate the sprite without rotating the collision mask.

Since rectangles are made of lines you could check line to line collision, something like https://github.com/processing/processin ... -Detection. If any line of Rectangle A intersects any line of Rectangle B then there are colliding.

Additionally one rectangle could be entirely inside another.

SAT collision detection may solve your problem. There is a tutorial of SAT implementation made by recursor but this might mean you have to change your collision detection script completely.

I'm actualling trying to understand the separating axis theorem but it seems to difficult. also i know hc but i prefer sat i think i'll try to understand. do you know a french tutorial for the sat because i'm not familiar with english language

i'll try to implement this also

the game i'm making is very similar to this one https://awesometanks2.com/ and if you can give it a look and tell me what kind of collision system they are using that would be very nice

May be will be usefull.
The main idea is to get the sum of the 2 shapes (hull). If the center of an object is inside a hull, the objects are intersecting.
In motion, check the intersection of the hull with a segment from the center of the moved object to its destination point.
