Prefabs not working correctly

[beo6]

When i use

local building = Prefab:Load("Prefabs/Buildings/"..pfbfile)

 

in my script, the Start function is not called and trying to call it manually with

building.script:Start() ends with an exception.

 

 

If i place it in the Map with the editor, the placed entity calls its start script, however

GetKeyValue("name") returns nothing.

 

When the Prefab is placed with the editor and i load another prefab with the script the loaded prefab calls its Start function and returns the correct GetKeyValue("name")

//Edited thread title as there is even a small bug when placing it with the editor.

Yes. i know that Thread, i thought it is obvious what the issue is. Sorry about that.

 

Have now created a project where i reproduced the issues. Hope that helps to fix them.

Press the Space key to call the Prefab:Load function.

the loading script part is in the gamecontroller.lua script.

 

There are two maps.

"callingStartFunctionButEditorPlacedDoesNotReturnName.map"

Where the prefab is already placed in the editor. There the prefab that was placed with the editor does not return the Name but the Start function is called. The by script loaded prefabs do return the name and Start is called.

 

"notCallingStartFunctions.map"

this one is without a placed prefab in the map.

There the loaded prefabs do never call Start.

 

It seems that the Start function is not called when the first load has Prefab.NoStartCall as parameter.

Then the prefabs loaded after that do still not call the Start Script even if that parameter is missing or i explicitly set the parameter Map.LoadScripts

[Josh]

Thanks for the files.

[Josh]

Okay, you just need to have Map.LoadScripts in your flags when the first Prefab::Load() command is called.

[beo6]

Thanks.

 

Using

Prefab:Load("Prefabs/myprefab.pfb", Map.LoadScripts+Prefab.NoStartCall)

 

seems to work.

 

But it feels a bit odd since calling only

Prefab:Load("Prefabs/myprefab.pfb")

 

for the first time does load the script. So it is not really clear that Prefab.NoStartCall does completely prevent loading the script and not only just prevents calling the Start function.

 

 

//Edit: what about that prefabs placed by the editor do not return their entity name with

self.entity:GetKeyValue("name") ?

The default parameter is the LoadScripts flag, so if you don't supply anything that is filled in:

ok. thanks now it makes sence.

 

still GetKeyValue issue on Editor-placed prefabs..

[Rick]

I think I'm seeing this prefab and GetKeyValue() issue too.

[DooMAGE]

Anyone with this issue too?

[Genebris]

Everyone has it.

[DooMAGE]

I guess josh is not aware of the issue.

[beo6]

i haven't tried it again if the issue is fixed, but if it is not, too bad Josh is ignoring my posts. Maybe someone needs to post the issue again in a new thread.

If you post a bug report with an example map that demonstrates a problem I will be happy to take a look.
