How to load models in Realtime from a blend file

Question

How can I load a model into bge in real time from a blend file with python? In other words when the game is running.

Answer 1

By default the BGE loads everything from a scene at scene start. To add more objects to a scene while the game is running you can use bge.logic.LibLoad() to dynamically load all objects from a scene of an external .blend file.

Be aware currently (since 2.78) this is supported:

• loading a single mesh (mesh - not object!)
• loading all objects of a scene
• loading an action

Sample code:

def loadAndMergeScene():
    libraryStatus = bge.logic.LibLoad(
        "//Asset.blend",
        "Scene")
    return libraryStatus.libraryName

To unload the merged data call LibFree(). The library name should match the one from loading.

def removeAndUnloadLibrary(libraryName):
    bge.logic.LibFree(libraryName)
