Placement of Custom Tiles

[Wizard Indie Games]

I have been having some minor issues placing my custom tiles in the level. They are 32x32 but sometimes there are gaps. I fix the gaps by placing overlapping tiles. They seem to fill the gap without actually overlapping adjacent tiles but sometimes they randomly decide to overlap when I exit Test mode or reload the project.

Also, tiles don't always get placed directly where the green rectangle is, even with Free mode switched off. What am I doing wrong?

I tried changing separation to zero but it didn't seem to make any difference.

Overall, I am very impressed by the app, BTW.

Antikore has a tutorial on how to fix this.

It's known as the "backline bug." Because of the way Game Maker blends pixels, you have to have a "cushion" around each sprite. It's kinda weird, but there's nothing you can really do to fix it within PB.

Thank you very much. I appreciate it!
