Title: Getting intersection direction/side.
Post by: fancode992 on December 15, 2019, 08:11:33 pm

Greetings,
As the title says, how can I get the side a sprite collides with another one? For example, I have an enumeration called "Direction" which includes north, south, west and east, a function shall return only one.

I am currently checking collision between two sprites via this code:

spritevar.getLocalBounds().intersects(spritevar2)

I am sorry for being so undescriptive. Thank you. :)

you should use sf::Sprite::getGlobalbounds() instead of the local to test for intersects.
you may try manifold for detecting the collision from every directions up/down or left/right, here an excellent tutorial in this topic with examples:
