Well I tried :
Minecraft.getInstance().runImmediately(new Runnable() {
@Override
public void run() {
MultiPlayerGui.this.minecraft.displayGuiScreen(new ConnectingScreen(MultiPlayerGui.this, MultiPlayerGui.this.minecraft, server));
}
});
And it's really weird...
In my console, I receive everything from the server chat. But on my game, it's stuck on loading the terrain infinitely !!!
MultiPlayerGui is my custome class but the rest is not..
I don't undersant why O_o
