So I've dabbled in Minecraft Modding in the past and just recently decided to give it another shot. I've watched and read a few tutorials about Key Binding and while trying to add a feature to armor that would allow you to change flight speed I've encountered a problem that I've looked around for some answers but haven't been able to find anything specific to my needs.
When using my Key Binding array in an IF statement whenever a game is loaded with the armor on I recieve a crash with the reason being a NPE and it points to my IF statement. I've attached the crash and the code in question and maybe someone who knows better will be able to help me out! If you need to see more code or have a question about the code or crash just lmk!
Code:
if (ClientProxy.keyBindings[0].isPressed())
{
if (player.capabilities.getFlySpeed() != 5)
{
player.capabilities.setFlySpeed(player.capabilities.getFlySpeed() + 1F);
} else {
player.capabilities.setFlySpeed(1F);
}
}
Crash Report:
[20:19:00] [Server thread/INFO] [FML]: The state engine was in incorrect state SERVER_STOPPING and forced into state SERVER_STOPPED. Errors may have been discarded.
[20:19:00] [main/INFO] [STDOUT]: [net.minecraft.init.Bootstrap:printToSYSOUT:629]: ---- Minecraft Crash Report ----
