How do I know if two 3D objects are not touching each other?

Does anyone know how can I know with two 3D objects are not touching each other? Just like Minecraft that two objects cannot be at the same space.

If they are at the same zelevation the normal 2d overlapping conditions work well. If you compare the zelevation too it’s possible to check for collisions on that axis too.

Another way is to compare the distance with sqrt((x0-x1)^2+(y0-y1)^2+(z0-z1)^2) <32 which would treat the objects as spheres.

There are more complex methods, but for now it’s best to skim other posts or examples for working implementations.

Thanks, I'll try that

I mean, It did detected if it was getting collision, but I am having another problem...

(BIG CODES!!!)

I am trying to do sort of like a 3D raycast, but this... https://www.youtube.com/watch?v=w-Bk8a4F9mw

This scares me :()

Is there any easier way? :3 (laughs in panic)

I found a portal gun game at Construct 3 templates. I think this is almost what I wanted, looks easier to understand... but... BIG CODES again (*screams*)
