Hi,
I have a problem with collisions.
I create an entity 16 * 16 which is my player.

I create a layer with TileSize = 16.

My player fails to pass between two blocks.

I do not understand why.

Thx for help.

The .pos.x/y in Impact is a floating point number. It's not rounded or truncated for physics calculations. So what you're seeing is an entity that's never perfectly aligned to fit between those two blocks.

E.g. lets assume you have two tiles at the following y coordinates 32 and 48. Now, if the entity's y position is exactly 32, it will fit in between those blocks. This only work in theory, because the entity's position might be 32.0003235 or something similar, but not quite exactly 32.

Long story short: make your entity smaller. 14x14 maybe. Give it an offset of {x:1, y:1} to center the image on it.
