As I'm planning to have spikes that hurt the player when it walk on them, and pits, the player falls down, I looked into tiletypes, at is much easier to check for the tiletype than to check for single tiles.
This raised some questions:
Blue field:
Is it just my server's configuration or has lava been removed? All the templates say that there should be lava, but I can swim everywhere in there and tiletype(x,y) returns 11.
Red field:
tiletype(x,y); returns 2, hurting underground. When you stand on there, your character slowly looses 0.5 player.hearts until he dies. Is there a way to stop that? I guess I could use some kind of loop and add player.hearts but maybe theres something like disablehurtinggrounds(); or disabledying(); or a serveroption I don't know about.
Green field:
tiletype(x,y) returns 10. I have found no documentation about that tiletype. Is it undefined? Well then I could use it for scriptinng purposes without having to worry about the game's features interfering.
Finally, is there a way to turn off the little animations by your feet when you stand in water or wamp or just change their look?
