kai is totally right, not a command, its a variable
anways you use it to set the tile at x,y to a certain tile
NPC Code:
if (playerchats) {
tokenize #c;
if (strequals(#t(0),changetile)&&tokenscount==4) {
if (strtofloat(#t(1)) in |0,64|&&strtofloat(#t(2)) in |0,64|) {
tiles[strtofloat(#t(1)),strtofloat(#t(2))]=strtofloat(#t(3));
setplayerprop #c, ;
}
}
}
