[SOL]Pressing 'K' in editor / killing a monster causes crash

[SpiderFighter]

I'm having an issue all of a sudden, pressing the instakill key within the editor, and killing monsters. I have added two snails and one herder, and killing (or pressing 'K' when in the editor) one of them always causes a crash, both in the editor and the exported game. The monster death that causes the crash can be different every time. I have no idea what's going on here.

Here's the error.log when pressing 'K' in the editor:

Does anyone have any ideas, or (or has anyone seen this before)?

[EDIT:} Ok, I'm not quite ready to mark this as solved yet, but I had a script like this:

SpoilerShow

local message = spawn("scroll")
message:setScrollText("VISITOR'S PASS")
visitora:addItem(message)
visitorb:addItem(message)

I had named one snail visitora, and a herder visitorb. I've deleted the "visitorb:addItem(message)" line and it seems to be working, although I cringe everytime I press 'K." I'll test it a few more times, because at one point I did kill both of them successfully (and had both scrolls in my inventory).

[EDIT: Calling this solved. Don't spawn one scroll and put it in two places. It might work, but, mostly...no.]

Yeah that's it, the error only "matured" when they died because that's when the game has to fork over the scroll, and suddenly it throws a conniption fit!

Yeah, seems pretty boneheaded, but the weird thing is that it actually did work at least once!

Code: Select all

local message = spawn("scroll")
message:setScrollText("VISITOR'S PASS")
visitora:addItem(message)
visitorb:addItem(message)

You cannot add the same object (= an object with a unique ID) to 2 different places. the first time you call "addItem" or "spawn" with exact placement coordinates, is the moment when the object "materializes" and cannot be "moved" by another addItem call.

What you should have done is call the spawn/setScrollText/addIem triplet two times. Like this:

Code: Select all

local alphabet = {"a","b"}
for i = 1,2 do
  local message = spawn("scroll") 
  message:setScrollText("VISITOR'S PASS")
  local recipientId = "visitor"..alphabet[i]  -- this generates either "visitora" or "visitorb" ID.
  findEntity(recipientId):addItem(message)  -- this finds an entity with that ID and gives it this "copy" of the scroll.
end -- at this point all the local variables minus the alphabet one disappear.

I've learned that I can't script worth a...well, I can't script. But this is a remendous help to us .lua newbies! Thanks for posting it.
