Happy Light Sandbox — sprite test playground

Sprite

No sprite loaded

Pose Scale 4× Pixels

Movement

Changes apply while you play and are saved in this browser.

Keys

Keys for the side view. Each view keeps its own set, saved in this browser. Click a key, then press the new one.

Pose keys — press one to play an attack, a block. Once plays it through and goes back to moving; Hold loops it while the key is down.

Hit box

Load a sprite to adjust its hit box.

The box the physics uses, inside the art. Saved for this sprite; the sprite file is not touched.

Camera

How the view follows the sprite. In pixel mode the zoom still lands on a whole number of device pixels per texel.

Background

Behind this level, in every view. Saved with the level.

Colour

No picture

Fit Parallax off

Pictures over 2048 px are shrunk; they stay in this browser.

Frame timing & angle

Blank means “use the pose’s own speed from Pixel Studio”. These stay here — the sandbox never writes back to your sprite file.

Levels

Controls

Everything stays in this browser — sprites, levels and timings are saved to this device’s local storage. No account, nothing uploaded.
