How to tell a module is on or off?

[commandblock2]

@chodeman
What I have been trying to do is to change

ScreenShotHelper.saveScreenshot(this.mcDataDir, this.displayWidth, this.displayHeight, this.framebufferMc)

to js.

Since it is in net/minecraft/client/Minecraft.java, the type of this is Minecraft (aka net.minecraft.client.Minecraft). And the instance of Minecraft is exposed as mc in scriptAPI.
So we change all this to mc.
But framebufferMc is not public so you cannot access it from a script.
So we accessing a private variable using reflection.
However the name of framebufferMc is not framebufferMc.
See about obfuscation.
You will have to use the Searge name(field_147124_at) to access variable and functions.
The file mcp-stable_22.srg have the mappings from MCP name to Searge name.
The reason you can use MCP name to in normal scriptAPI is because they did this.

But with Core.lib you don't have to do that anymore.
@CzechHek
THANK YOU BASED HEK. Don't have to look for srg name anymore.
And that should even solved the problem of using script in development environment, going to try it later.

[idk my name]

@commandblock2 dafuq, thank you!
I did not know what do some fields mean, they do not exist in mappings (1.7-1.12).
I used srg file and now know, what does this field mean

@czechhek You have actually changed the way I code scripts, thanks
