I made my own keybindings and registered them, they worked fine, but when I opened the "controls" screen to edit keybindings, the game crashes

 

Am i doing anything wrong?

You have a null pointer exception occurring in GuiListExtended for whatever reason:

Caused by: java.lang.NullPointerException
   at net.minecraft.client.gui.GuiListExtended.func_148181_b(GuiListExtended.java:70) ~[GuiListExtended.class:?]
   at net.minecraft.client.gui.GuiControls.mouseMovedOrUp(GuiControls.java:111) ~[GuiControls.class:?]
   at net.minecraft.client.gui.GuiScreen.handleMouseInput(GuiScreen.java:349) ~[GuiScreen.class:?]
   at net.minecraft.client.gui.GuiSlot.drawScreen(GuiSlot.java:314) ~[GuiSlot.class:?]
   at net.minecraft.client.gui.GuiControls.drawScreen(GuiControls.java:148) ~[GuiControls.class:?]
   at net.minecraft.client.renderer.EntityRenderer.updateCameraAndRender(EntityRenderer.java:1143) ~[EntityRenderer.class:?]

I don't have MC code open at the moment, so I need ask, is GuiListExtended your class, or a vanilla class? If it's your class, we'll need to see the code for it; if not, then whatever you are doing to access func_148181_b is causing a null pointer.

Something in your environment is registering a keybinding that's null.

Check the load order of your calls.

 

I do Forge for free, however the servers to run it arn't free, so anything is appreciated.

}

 

Can I ask why you are making your own class extending KeyBinding? Why not just use new KeyBinding(name, key, category)?
