I wanted to hide coins behind priotized ground tiles but it doesn't work, any anyway around this? How about doors/pipes. Only way I can think is to make those ground tiles act like what I need
Code
PHY ; \ LDA #$02 ; | STA $9C ; | Erase tile JSL $00BEB0 ; | PLY ; /
Next one, replace it with the following code:
Code
REP #$10 LDX #!block_number %change_map16() SEP #$10
Just keep in mind that you first have to change "!block_number" into the Map16 number where the dirst tile is and I also assume, if you use GPS.
Blocks which doesn't change its tile can be easily done with just changing the act like setting.
Edit: Hooray for yoshicookieninja. At last my answer for his first question is more helpfull then YCN's one. :V
