I want to make it where when you pick up a key a phanto chases you.

Code: Select all

local player = Player();

function onLoop()
   if(player.holdingNPC ~= nil) then
      if(player.holdingNPC.id == 31) then
	  Phanto:hide(true noSmoke)
	  Phanto Chasing:show(true noSmoke))
      end
   end
end

local player = Player();
local Phanto = .... -- here must me a construction of the layer pointer
local PhantoChasing = .... -- same
function onLoop()
   if(player.holdingNPC ~= nil) then
      if(player.holdingNPC.id == 31) then
	  Phanto:hide(true)
	  PhantoChasing:show(true)
      else
          Phanto:show(true)
	  PhantoChasing:hide(true)
      end
   end
end

What's a layer pointer?

Edit:
I would use this code but it gives my game severe lag.

local player = Player();
local Phanto = Layer.get("Phanto")
local PhantoChasing = Layer.get("Phanto Chasing ")
local holding = false
function onLoop()
   if(player.holdingNPC ~= nil) then
      if(player.holdingNPC.id == 31) then
          if(holding==false) then
	         Phanto:hide(true)
	         PhantoChasing:show(true)
                 holding=true
          end
      else
          if(holding==true) then
               Phanto:show(true)
	       PhantoChasing:hide(true)
               holding=false
          end
      end
   end
end

If not, how would you define a function that does? When deleting save files, do you have to delete any other files?

Also you mean the game save files for slot 1-3? If so, then no need to delete anything else.

That's a bit odd, because I'm pretty sure variables defined without the "local" keyword will work across all files in a world (which can and will screw you up if you don't know what your doing, like me!)
Also, are global variables somehow stored inside the save file (or some other way?), or are they just thrown out when you quit the game?

_G["myGlobalVariable"] = 5

local myVariableFromGlobal = _G["myGlobalVariable"]

If you use the data class, will it work across play sessions? And if so, does the player have to save the game for it to work across play sessions?

Probably. How are you changing what item the hammer brother throws in the first place?

Kevsoft wrote:Generally by modifying the id of the npc. So every new hammer is transformed to a new one, which means that you cannot have any hammers in your level.

--To change hammers into an npc of the given id on a per-section basis (or whole level)
function swapHammers(npcID, sections)
	sections = sections or -1 --if sections is nil, make it -1
	local tableOfHammers = NPC.get(30, sections);

	for i = 1, table.getn(tableOfHammers) do
		tableOfHammers[i].id = npcID;
	end
end

--To change on a per area basis
function swapHammersIntersecting(npcID, x1, y1, x2, y2) --WARNING: don't make areas too close
	local tableOfNPCs = NPC.getIntersecting(x1, y1, x2, y2);

	for i = 1, table.getn(tableOfNPCs) do
		if tableOfNPCs[i].id == 30 then
			tableOfNPCs[i].id = npcID;
		end
	end
end

--Whichever comes first in onLoop function will take priority
