@kirinnee97 @diesieben07 Seem to have done the trick Thanks for the help.

@kirinnee97 @diesieben07 Im testing using : player.world.isRemote So far no crashes. Ill let you know when I've finished testing. Thanks for the help!

@diesieben07 All I want is the player to answer the question and if its right they are given an item as a reward. This is for a singleplayer mod.

@kirinnee97 Do you have any good examples for sending packets that deal with the Gui? I have only used packets to give items to the player. Thanks. @diesieben07 I see. And I guess in this instance that behaviour is the random crash.

@diesieben07 Thanks Ill have a read now. I've been stuck with this for a while. It works fine but randomly crashes. Am I just calling it wrong?

@kirinnee97 I do already do that if you look at my code.

@diesieben07 I open the GUI from the BlockMathsAdditionBlock https://gist.github.com/MarkWatt3295/103b6a5b8b1976a8f18ceef48ae7cf48

Hi there. I've been trying to create a basic Gui for my Mod. The Gui has a background, a text input, buttons and has strings drawn on. My Gui displays and functions correctly but every now and then it will cause a fatal crash. The crash happens randomly. Sometimes when I try and display it, it will instantly crash. Other times I can open and close the screen multiple times with no issue. The Gui is called by right clicking on a block using: Minecraft.getMinecraft().displayGuiScreen(new GuiAdditionBlock()); My Gui class can be found at : GuiMathsBlock The Crash report for it can be seen at: Crash Report I think the error is being created with drawing strings as fontRendererObj is being set to null somehow (You can see the print statements in the crash report). To test this I created an even simpler GUI screen that had just a background and a button. This also crashes but threw a different error. Can anyone see what i'm doing wrong here? Here is the other Gui made : The Even simpler Gui Crash report from that one : crash report I've attached images of the working Gui but the upload has failed. Please let me know if you have any suggestions or need more details. Heres a quick video if my bug. (Video is a little laggy) : GUI Bug Thanks.
