Grimrock

It still works with current Blender versions, the imported object rotation/scale are just wrong sometimes but this is not too annoying to fix.
To get the correct layout in Blender to export a Grimrock model, import an existing model, look at the object hierarchy, and match it (I often do so by importing a model, deleting the existing mesh, and copying my own mesh object into it). Your object hierarchy should look something like this:

If you have a rig then it's a little more complicated: The Blender plugin uses empty objects for nodes; every empty object except game_matrix will turn into a node, as will every mesh object.

Thanks again minmay and Isaac. I think I understand where I was going wrong now.

Is it possible to add a function to a script entity with a console command?

One would think so [ via setSource() ], but in practice it doesn't seem to work.

I just tried many things, but it seems completely impossible.

I thought I could somehow patch the mod I shared recently, but any additional code is not allowed after the game has started:
- You can't add a function (except in the GameMode table!)
- If you ignore the compatibility warning and load your old save game file, the definitions of new objects in the new mod version are never defined, the init phase occurring only once.
- You can't spawn a script_entity and set or load its source, it will never execute.
- You have no way to build an object dynamically and define its components' functions.

So, I think there is something done to the lua code on the game start that can't be done later or is forbidden for some reason.
It appears all possible ways are intentionally locked.

You actually can do this by calling setSource() or loadFile() before the ScriptComponent fully initializes.

To do this you would need an object definition with this call, and you can't define a new object when loading a save from a previous version of a mod.

But I suppose I could define a "patch" object which just does this for future updates.

I'm having issues with id setting.
For some reason, when I place an object on the map that creates other objects and uses self.go.id.."_p" to set their IDs, everything works fine.
But when I spawn that object with a spell, it says "invalid entity id".
Any way to work around this?

Here's the line I'm using to spawn objects through the summoned object: EDIT: I got it. the ID cannot start with a number, so I'll just rewrite it to this:

How is "self" defined when used in the spell? My guess is self.go.id returns nil in your context.

No, because like I said, the spell spawns an object that spawns an object.

EDIT: Never mind, figured it out. Read my previous post.
