Something like this perhaps?

Code: Select all

party.party:spawn("dagger")

party:spawn("dagger")

I think I have seen the answer somewhere, but I can't find it now. I want to retrieve four objects previously spawned to move (or destroy) them. I know theirs positions, but not their id (spawn). I tried "EntitiesAt" but nothing happens... Perhaps it's necessary to store id on spam, but is ugly... Using floor triggers? Some help please

If you know what they are, you can compare by name instead of id. Use entitiesAt() to loop though the contents of the cell, or use the contents() method if the objects are on [in] a surface component.

This should work, unless you have a pile of like objects, and are wanting a specific one.

function makeessence()
	for px=2,4,2 do
			for py=16,18,2 do
				for e in party.map:entitiesAt(px,py) do	
					if e.name=="power_gem" then
					e:setPosition(3,17,1,0,party.level)
					end
				end
			end
	end
end

 The way this works is to spawn a timer and floor_trigger on the tile where you place the script object.
 At runtime, any item placed on the ground will activate the timer to check that tile for the target item.
 The timer remains on until the items are removed.

You are using the loops for a single value each. You do not need a nested loop for that.

You could try this script for the same effect:
Place either your timer, or trigger/switch ~or even your calling script on to the specific tile that you wish to check for your items;
and connect it to this script.

Thanks for your help.
I understand the idea, but I have four locations to check, so I can't put the script on it. You means that my script is more CPU consuming than 4 floortriggers plus a timer? A silly ask: what is ift in your script? I don't see where are ift values??

Uh, each loop runs twice, for a total of four iterations of the inner loop.
