Now, I don’t know if this is just me being dumb but when I try to move my sprite (9x9)’s y from 79 to 80, it moves more than 1 pixel. I then tried it again, this time from 80 to 81, and it moves as intended. There are no other codes overriding the sprite’s y axis by the way, and it seems that all sprites on 79 y are affected as well(as seen in the first row of yellow squares). Also yes, I’m making a Makecode Version of Minecraft.

@Trr this is probably because of the tilemap. make sure you have the `ghost through tiles` flag turned on for the sprite

Well this is weird, I have tried all the ghost properties but it still doesn’t work. I checked the physics of that sprite and its y is 75 in the game but 79 in the editor. I found a workaround by using 80 instead but I will still have to test it around, thanks though!
