Creating Unit Art

Here's the information needed to start doing units art for Wesnoth. Please update the wiki with links to examples and other tips and tricks realted to unit art. This page started from this forum thread.

Basic unit image specifications

• Final format: transparent PNG, 72 x 72 pixels
  • 8 bits per RGB channel. may be listed as "PNG-24" or "8-bit RGBA".
  • "Indexed color" or "color map" is different. These will work, but are not recommended.
• All but exceptionally large units should be contained in the hex (the white in the attached template)
• Compare the size of your unit to the size of similar existing core units
• Light comes from a specific direction (for shadings and highlights)
• Unit must look in the lower right direction
• Units are centered horizontally
• Unit's feet are positioned around 55 pixel from the top, lower for taller units if necessary
• Shadows at 60 opacity, black color (with blurred and soft borders, see Creating_Shadows_Under_Units).
• Outlines should be used, made with a darker, but similar colour to what they're surrounding, this makes the unit feel bigger then the amount of pixels you'd use for the same with a black outline. (Black outlines not welcome anymore)
• Use consistent names for your files, beginning with the unit name, so that they are kept together when browsing the files.

Unit animation specifications

• You can have as many frames for animations as you like. It depends on what you want to get accross
• Images and animations must be done for:
• normal image (1 frame)
• attack for each type (at least one frame - 2 is good - 4 better)
• directional attacks (spear and ranged)
• defense
• magical attacks should have 'special effects'

You can also have multiple defense animations (like the thief.) Defense can be split into ranged and melee animations.

It is important that the unit moves its feet when doing a melee attack. During the attack the unit will move from its own hex to the hex it is attacking. If you don't have feet movement in your animation, the unit will be "sliding" toward it's target, which looks bad.

Additional Notes and examples

• Test early with different backgrounds. Go to your game terrain files, pick, say, 3 terrains, preferably with different colours, and have a look what they look like against the background, because that way if you have used alpha channels, it may look better in game than as the average standard sprite.

• Test your unit early in the game. Replacing an existing unit graphic with yours is the fastest way (be sure to make a copy of the originals so you don't lose them.)

• If you are animating a horse, you should base it on this example of an horse animation
