Tilemap tiles has wrong display #17257

HikkaKun commented 4 months ago

Cocos Creator version

3.7.4, 3.8+

System information

Windows 10

Issue description

If you are using Tilemap where multiple tiles is packed into a single image, the tiles has wrong display at the edges (looks like it crops 0.5px of the tile texture on each side) and tiles don't look seamless too

image

I blame these lines of code because if you are using multiple images for each tile or just one tile in the tileset - the tile has the right display
