Snippets about gamedev

Wait a second in GDScript

Pause a function without blocking the game, the Godot 4 way.

Export a sprite sheet from Aseprite's command line

Put the export in a script so every save of the .aseprite file can rebuild the sheet.

Lerp and clamp

Two one-liners every game and animation ends up needing.

Crisp pixel art on a canvas

The canvas smooths scaled sprites too. Turn it off, in two places.

Seeded random numbers in JavaScript

Math.random() can't be seeded. For procedural levels you need one that can.

Pick a random element in GDScript

Random loot, random lines, random enemies. Godot 4 has it built in.

Pixel-perfect settings in Godot 4

The project settings that keep pixel art sharp when the window is scaled.

Shuffle an array properly

The sort(() => Math.random() - 0.5) trick is biased. Fisher-Yates is just as short and actually random.
