Well, I got the mod Spawner GUI and it's pretty cool, but I noticed it will only let you change the spawner in creative mode and NOT survival, Is there any way I can configure this? Please let me know!
You won't be able to configure it in survival mode. There are no mods that will allow you to configure it in survival mode either. You will have to make a survival world and activate cheats. Then you can create your world make your spawner and then switch back to survival mode.
There is an alternative. MCedit. There is no need to install mods and it is an open source program. http://www.mcedit.net/ It is a world editor, so you can edit things with out enabling cheats.
