Problem with layers and the transparent tile.

[cchmaster]

Now I've used 3 layers:

Layer 1 is the bottom ground.
Layer 2 is some highlands, which are walls and the top platforms.
Layer 3 is decoration, which are flowers, logs, and etc.

My problem is, when I was on layer 3, I misplaced some logs, so I used the transparent tile(from A5) to erase it. However, after that, those tiles couldn't be passed through anymore.

To experiment, I tried to flood fill my map with the transparent tile on layer 3. Now I couldn't walk at all, no matter where my character is, even on the bottom ground.

So, I changed the transparent tile to be passable and flood filled layer 3. Now the whole map can be walked through, even walls.

Can anyone please help me how to solve the problem? How can I delete the "transparent tile"?

basically you used the wrong tile to erase - you should have used the very first B tile for this.

and the reason is that the erase tile should always have the star passability, because in reality there is no "erase" at all.

each tile is coded by a number, and each map position is the equivalent of a variable to hold one number each layer. You never erase anything, you only fill the position with a different number of a tile to be used there.
and the star passability is the only one that says "ignore me for passability, look at the other tiles to determine passability". every other tile WILL set a passabilty or impassability for the place where you use it - even if the tile itself is invisible.

EDIT:
and another advice - don't get your mind fixed on what to use layers for. Sometimes that is superseeded by what the map needs, like two decorations above a wall - you never need a ground if a tile is completely covered by a wall.

@Andar WOW! Thank you so much, friend. You've just saved my world. I don't know what I was thinking. How come I tried so many things, but didn't give the B transparent tile a try.

Really thank you, and for the advice, too. I'm new to RM. Listening to experience from veterans is great. Thank you again!
