Eclipse解决类型错误

The source is at https://github.com/Derivates/fpsmod_1.12.2/blob/master/src/main/java/me/dewgs/fpsspoof/FPSSpoofModCommand.java

Here's the log:

And also here's a screenshot:

I'm not sure if the issue is caused by a missing class which isn't present in the original jar file.

Answer 1

In the screenshot you provided, you showed that you were sending a message by doing Minecraft.getMinecraft().player.sendMessage which means that the command will only work client side and will cause a crash server side.

The method already adds the ability to send back through the argument sender which allows you to access to the sendMessage method which will work server side as well as client side sending a message to that entity.

Also, ChatComponentText is now called TextComponentString I believe.
