[[solved]Forge in Eclipse not working properly]

Hmm....check Run-->Run Configurations and make sure Client is:

 

net.minecraft.launchwrapper.Launch

 

...and Server is:

 

cpw.mods.fml.relauncher.ServerLaunchWrapper

 

Also, please make sure your Eclipse Workspace is forge/mcp/eclipse and *not* forge/fml/eclipse

 

(Project-->Properties, then Resource.Location)

 

Mine is forge\mcp\eclipse\Minecraft

[Get the block(or blocks nearby is ok) which player is looking at]

In 1.6.4, try EntityLivingBase.getLookVec()

 

Player is an (extends) EntityLivingBase.
