Hallo,

with the following script i add a tiptrigger form a vehicle:

self.trigger = Utils.indexToObject(self.components, getXMLString(xmlFile, "vehicle.trigger#index"));
table.insert(g_currentMission.tipTriggers, TipTrigger:new(self.trigger));


but if i sell the vehicle then is there a lua error:

Lua: Unknown entity id: 24432 method name: getTranslation
Callstack:
dataS/scripts/triggers/TipTrigger.lua@77 (getTranslation)
dataS/scripts/BaseMission.lua@760 (update)

do you check that self.trigger is no nil?

You have to make sure, you remove your trigger from the g_currentMission.tipTriggers array (search for it an delete) in the delete method of your vehicle.

If you sell your vehicle, the root node of the vehicle as well as all its children are deleted, including the trigger node, thats why it says "Unknown entity id".

Yes i know after sell the vehicle that the trigger(object) no longer exist.

table.remove(g_currentMission.tipTriggers, self.trigger);
or
table.remove(g_currentMission.tipTriggers, TipTrigger:new(self.trigger));
does not work.

Can you write the Code for delete the trigger-entry of the table g_currentMission.tipTriggers?

for i=1, table.getn(g_currentMission.tipTriggers) do
if g_currentMission.tipTriggers[i] == self.trigger then
table.remove(g_currentMission.tipTriggers, i);
end;
end;

I wrote this in the delete function of my script but it does not work.
I get the same lua error

The problem is, your insert code looks like this:
table.insert(g_currentMission.tipTriggers, TipTrigger:new(self.trigger));

Then you can't search for self.trigger in this map.

You should do something like this:
self.triggerObject = TipTrigger:new(self.trigger);
table.insert(g_currentMission.tipTriggers, TipTrigger:new(self.triggerObject));

And adjust the "if" in the delete code:
if g_currentMission.tipTriggers[i] == self.triggerObject then

I changed this but i have always the lua error

The Trigger is in a Mod Vehicle, not in a Map.

Does anyone know an answer?

Unfortunately a cant reproduce the error.

I bought and sold the tool. All works without an error. Do you have any other mods installed which might change any functions of the game?

0.0 you have right. I have only the Mod at the mods folder and it works.

Thank you for the Support.
