how to create a user-defined engine

[lancer_xjb]

first,the user can see a gui interface.Then the user selects the parameters of irrlicht engine. Finally, the specified engine is created and rendered.
I created a device = 0,and use it to create a gui interface such as
Device->getGUIEnvironment()->addButton(parameters).
But there is always an address problem with the device;.
How to solve it?Or how to created an upper device?

Sorry, your question is colorful but lacking information.

I suppose you want to create 2 devices in a row. First one for settings, then one for the game. You have to close the settings device with device->closeDevice (). And then create a new device with createDevice or createDeviceEx. If you have any errors while doing that, then please show us the code and tell us in which environment (OS, compiler) you have those problems.

What you do is equivalent to "0->getGUIEnvironment()" it won't work.

Create one device first then grap the parameters you need. Del the first device (->closeDevice) then create a second device with those parameters.
