How to check?

[ziomekzlasu]

Hi everyone. Sorry for english. I don't have idea how to make function, that will check if on tile is item. For example - i have tile with id 190. If on this tile its ANY item (border, moutain, tree), funciton will return false.
Something like that :
if checkTile(x,y,z) == true (free) then
bla bla bla tile is free
else
bla bla bla tile is blocked

Can you make it for me?

function isPosClear(pos)
    local tile = getTileThingByPos({x=pos.x, y=pos.y, z=pos.z, stackpos=0})
    return (tile.uid ~= 0) and not hasProperty(tile.uid, CONST_PROP_BLOCKSOLID) and not getTileInfo(pos).protection and not getTileInfo(pos).house
end

That should work...

Almost it works. When blocking item is on pos it returns false but i need function which return false when any item is on pos (no blocking too ;P ). So how to fix it? But thanks so much you get rep++. That function made my system much better.

Try this:

function isPosClear(pos)
    local tile = getTileThingByPos({x=pos.x, y=pos.y, z=pos.z, stackpos=0})
    local item = getThingFromPos({x=pos.x, y=pos.y, z=pos.z, stackpos=1})
    return (tile.uid ~= 0) and not hasProperty(tile.uid, CONST_PROP_BLOCKSOLID) and not getTileInfo(pos).protection and not getTileInfo(pos).house and not item.itemid
end

Maybe that works... :S

Yes, thanks a lot - it works correctly. Can you help me with next problem? My script random draw a position from whole map. If on this position is blocking item, it will draw again. (thanks to you) But there are tiles wichout items/ground - just blank. When script draw blank position it makes error in engine log - i really dont like it. What condition i should do? I tried something like (its repeat loop) repeat .... until getThingFromPos ~= 0 and isPosClear == true. But i really thank you for that what you do
