Tile Asset Builder

Overview

The entry point for building tile assets. Bulk-slice a sheet image into static tiles, swap some slots to animations, define multi-cell stamps such as a 2×2 house, and merge existing auto/rule tile assets — all into one TileAsset. Slicing, selection, and naming are edited in the dedicated editor (Tile Asset Builder); the node itself only evaluates the recipe (builder_data).

Usage tips

• For bulk registration connect either image (you specify margin/spacing yourself) or sprite_sheet (columns and cell size carry over). No per-cell wiring is needed.
• For animations, setting a "target brush ID" swaps a static tile to an animation while keeping its public brush ID (and thus its palette slot). Frames come from the images input (all frames the same size) or from cells on the same sheet.
• Save the finished asset with tile_asset_save as a self-contained .pxntile — it loads even after the original input nodes are deleted.
• While warnings reports "live source" issues, resolve them before saving anything meant for distribution.

Common pitfalls

• Animation frames with mixed sizes — pad/crop them to one size explicitly before feeding images; no implicit correction is applied.
• Transparent cells get registered — set the slice recipe's transparent-cell policy to exclude_fully_transparent to skip fully transparent cells (row/column positions are preserved).
• A connected auto-tile isn't imported — the recipe's "include rule asset" toggle (a checkbox in the editor) must be enabled.
