Clone Minecraftforge to build own version
I'm not sure if this is the right place to ask, but I need to do an urgent hotfix for Minecraftforge and therefore I want to clone the Github repo and build my own version. I've tried this before, however with no success. Can someone give me a brief introduction? I have good knowledge of git and I use Eclipse. @diesieben: If you read this, would be cool for you to come online in Skype if you wanna help me. Thanks in advance, CrushedPixel

Client Side: Test if OP on a Server
Lol I guess I'll run a simple command then that doesn't affect the world (e.g. /testfor @a[r=1]) and check if it denies permission.

Health Boost Not Regenning
You should have a look whether you are cancelling any Regeneration Effects somewhere. Also, you might be applying the Health Boost effect for a very short time and / or over and over again. The key is to apply the effect only once when it's necessary and remove it later.

Client Side: Test if OP on a Server
Is there a simple way to test whether mc.thePlayer is OP on a multiplayer server? Client side, I don't want to mod the Server.

[SOLVED] Client Side Mod: Teleport Player on Server
I guess this can be locked as "Solved" then - many thanks!

[SOLVED] Client Side Mod: Teleport Player on Server
Hmm, I think I'll just require OP for the mod then. Would be overdone, especially because when flying over a larger distance chunks might not get rendered etc.

[SOLVED] Client Side Mod: Teleport Player on Server
I've already done that in the Replay Mod. How can I add this custom entity to the world the client receives?

[SOLVED] Client Side Mod: Teleport Player on Server
I'm pretty sure it doesn't, as F5 showed the player. How to actually move the camera? Any tutorial links?

[SOLVED] Client Side Mod: Teleport Player on Server
I've recreated the Camera Studio Mod for 1.8 using Forge, and the only part that's missing is the initial Teleport and/or Goto. How might this work in Camera Studio for MC 1.7, since it does NOT require OP there?

[SOLVED] Client Side Mod: Teleport Player on Server
Is there a way to teleport a player over a rather large distance (> 100 blocks) while he is on a server? calling mc.thePlayer.moveToBlockPosAndAngles and similar methods just result in the server teleporting the player back. I need it for a waypoints system I'm creating - Server side mods are not an option. If necessary, OP can be a requirement.

[SOLVED | SWITCHED TO ASM] Javassist not working with ModClassLoader
As the aim of this mod is to simplify mapmaking/command block creations, that would be kinda counterproductive. A quick showcase on the finished mod btw if anyone's interested:

[SOLVED | SWITCHED TO ASM] Javassist not working with ModClassLoader
Without modding the server, that wouldn't be possible though.

[SOLVED | SWITCHED TO ASM] Javassist not working with ModClassLoader
Trust me, I would've done that if I could have, however the Minecraft class calls the NetHandlerLoginClient, which then instantiates the NetHandlerPlayClient. In order to do the desired manipulation, I would have had to extend the NetHandlerPlayClient, but there was no point where I could replace the default PlayClient with my custom one. So I had to use the dirty Bytecode Manipulation way.

[SOLVED | SWITCHED TO ASM] Javassist not working with ModClassLoader
What exactly do you mean? All of the Forge+ASM tutorials I found used this technique.

I've switched my code to use ASM now - it works perfectly fine!
