What Sprite Animation Previewer does

A walk cycle that pops or slides is hard to see in a still sheet and obvious the moment it plays. The Sprite Animation Previewer plays a sheet the way your game will: it finds the grid, plays any row at the speed you set, ping-pongs it, flips it, steps frame by frame and puts it on a dark, light or green background.

Onion skin shows the frame before in red and the one after in blue. Frames drawn off-centre, the ones that make a sprite wobble in the engine, are counted and marked, and one tick lines them up on their feet or their middle. Save the fixed sheet as a PNG, the animation as a GIF for your devlog, and a Godot 4 SpriteFrames, or all three in one ZIP.

How it works

  1. Drop a sprite sheet or several frames on the box (or try our knight).
  2. Check the grid, pick the animation and set the speed, ping-pong and onion skin.
  3. Look at the marked frames and tick Line them up if they wobble.
  4. Download the sheet, the GIF and the Godot SpriteFrames.

What you get out
