There are three solutions below. Here I recommend the second solution because it is fast and simple enough.
Phenomenon :
Solution 1 :
Refer to [Unity2D] Remove the black line in the map_unity is selected and wired_Mushroom CST blog-CSDN blog , the blogger explained that the problem is caused by anti-aliasing sampling.
Specifically for this game, there are two steps:
Yes Tile Set.png, modify pixel per unit, if the original ratio is 16, reduce it to 15.9
and then use the tiles as in Part1, just re-pave it again, the white line gap is unity2022unique, I have tested that 2021版本only the black line appears.
Solution two :
Refer to the "line" problem between the video content of Part3 and the tiles in Unity 2d game development - Yuluo Jiangzhou - Blog Garden (cnblogs.com) This article content, change the default material.
Add a new material
, check the pixel capture
, and then attach this material to the material properties of the tile map rendering.
Solution 3 (I have not verified it) :
Refer to Solve the Tilemap Gap Problem in Unity | I am a monster ~ Liao Yulei (dualface.github.io) This article can be dealt with.
