LoS / gameboard object

[Panchos]

I'm tryin to use the advanced gameboard object to achieve a line of sight in my game. I want all squares that aren't behind a wall (obstacle) to be seen. Eg:

If that door were to open, the player would be able to see all the squares inside the room. If the player was inside that room and the door was closed, then every other square on the grid wants to be hidden.

basically, perform a flood fill from the square of the player, everything touched and everything adjacent to something that was touched becomes visible. everything else is hidden.

i figured the advanced gameboard object was the best thing to use for this?

If anyone could give me some code tips or whip me up an example that'd be great. Or maybe there's a more effective method?

Well it's not the advanced game board object you want:

It's not perfect but you can see what I'm getting at...

Thanks but my levels are generated at runtime from a map txt file and i can't have preset roof shape objects.

Hm, ok that complicates things!

I'm not sure what to do!

[Panchos]

Me neither

Maybe you could use the Mine Sweeper technique. I made an example in a thread a while back, I'll see if I can find it again...

EDIT: After a while of searching, I found it:

Thanks for your help I tried that method in my game and the tiles disappear too slowly and it wouldn't work for a field of view or line of site effect.

Sorry to be a pain- I'm not being ungrateful

Well the idea was to do it in a fastloop until all the tiles had been checked.

If you just want the affect and don't care how you get it...
you can always just teleport the player to another part of the screen when the character enters the room.

I don't think I understand, how does that solve this issue?
