Attempting to call a method of an entity from another entity

[Raxe88]

This is my code:

 

DeathTrigger.lua (attached to a box)

Script.respawnPoint = "" --Entity "respawn point"
function Script:Collision(entity, position, normal, speed)
if(entity:GetKeyValue("name") == "Player") then
spawnPos = self.respawnPoint:GetPosition()
--entity:SetPosition(spawnPos)
entity:Respawn(spawnPos)
end
end

 

and

 

FPSPlayer.lua (attached to the player)

function Script:Respawn(spawnPos)
self.entity:SetPosition(spawnPos)
end

 

When they collision I get this error:

 

 

I have a Pivot indicating the respawn point:

 

Line 65 is this from DeathTrigger.lua:

 

entity:Respawn(spawnPos)

 

From my point of view it should work. Any help?

 

Edit: I just found it out. Turns out that this works:

entity.script:Respawn(spawnPos)

 

A little explanation would be welcome

The entity and a script attached to that entity are 2 different things. You can get either from both.

 

entity.script or (inside the script) self.entity (note that when inside a script 'self' refers to the script itself NOT the entity)

 

The collision callback is returning to you the entity NOT the script. So in order to call the script functions attached to the entity you need to access the script variable of the entity.

 

entity.script:Respawn()

 

Now entities do have functions (as you see in entity:SetPosition()) but those are C++ engine commands on the entity. The scripts are different than the built-in engine functions. This whole script thing is something that didn't exist in the early days of LE but something like SetPosition() has existed since day 1. Scripting functionality was added later after the core engine functions were already there.

Thanks a lot for the answer! This is something I didn't know and is important.
