First off, this is most likely a Minecraft issue and not a Forge bug.

 

I am registered to receive the GuiOpenEvent in one of my classes and noticed that it gets fired twice for GuiGameOver. Once when the GUI is first opened (expected) and again when it is closed by clicking the "Respawn" button (unexpected). At first I thought it may be because the GuiGameOver screen creates a 2nd new screen, GuiYesNo, after clicking the "Title screen" button but in both cases event.gui.toString() is still "net.minecraft.client.gui.GuiGameOver".

 

To reproduce this, simply get to the death screen by typing "/kill" and notice that the GuiOpenEvent fires twice.

 

I am using Forge 1.8-11.14.0.1261.

What is the stac of both?

it wouldnt be us firing it twice, it'd be the game doing it.

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

Sure enough, when "Respawn" is clicked, Minecraft decides it wants to open a new null screen, which the game then interprets as a GuiGameOver because the player has <= 0 health. So it is just an unintended side effect of some bad coding from Mojang.

 

I used this to my advantage by using the following logic:

if(mc.currentScreen != null)
{
//"Respawn" is clicked
}
else
{
//GuiGameOver is initially displayed
}
