TileMap.createFromTiles doesn't properly handle multiple tilesets

[vikerman]

Version

• Phaser Version: 3.88.2

Description

Tilemap.createFromTiles with useSpriteSheet specified in the SpriteConfig assigns the frame number just using the current tile index without taking into account that the tile index doesn't always start from 1 for all tilesets other than the very first one.

Example Test Code

https://stackblitz.com/~/github.com/vikerman/my-phaser-game

The sprites created from the second tileset are all wrong

To test the fix locally comment lines 221-230 and uncomment lines 233-242 in Game.ts in the StackBlitz .

Sprites are properly created after the fix

Additional Information

The line at

phaser/src/tilemaps/components/CreateFromTiles.js

Line 86 in c62baca

config.frame = tile.index - 1;

            config.frame = tile.index - 1;

needs to be changed to

             config.frame = tile.index - tile.tileset.firstgid;

Tested the fix locally by creating a secondary copy of createFromTiles in my project and applying the above fix.
