In Hedgewars, every hedgehog can optionally wear its own hat as decoration. They can be selected on a per-hog basis in the team editor.

There are two types of hats: normal hats and team hats.

Team hats are hats which will be colored accordingly to the team color.

I.e. if a hedgehog plays in a red team, its hat will we red.

These are the simplest hats. It's just a single 32×32 image containing the hat. This image will be put on the hedgehog's head with a vertical offset of 5 pixels.

This is a 64px×32px image with 2 frames. The left half is the base coloring of the hat, the right half should _only_ use grayscale colors for the parts of the hat for which to use the team colors. The left part may be even completely blank. The same offset of 5 pixels applies here.

The team hat image consists of two “halves”: The left half is the base coloring of the helmet, the right half should _only_ use grayscale colors. The left part may be completely blank. So you have basically two sets of helmet animations. Again, both animations have exactly 19 frames, the remainder is unused.

Transparent pixels on the right part will not be overlayed. This way, you can decide which parts of the helmet become colored and which won’t.

For static hats, this is trivial: Hedgewars will just move the hat up by 5 pixels before drawing it on the hedgehog.

This is how to read this table: If you would like to create a simple hat with no fancy animation, like, let’s say, a fedora, you would like the hat to “follow” the hedgehog. You could, for example, draw and align the hat image on the first frame, then copy it on all other frames and apply the offsets to the four “special” frames.

Use these images as a temporary background layer. They show a colored checkerboard pattern, each field represents an animation frame. The green and red fields are those where the idle hedgehog has an offset of +1px or −1 px (see above). The black fields are the unused frames.

In the front, the idle hedgehog can be seen, already shifted correctly. The gray hedgehogs remind you of the fields which need to be in grayscale for team hats.
