Thanks you Tobias and Cerberi_croman , though with A7 native MP code that i am using , the server player and enemy react as expected but only when client player comes close to the enemy , the invlaid you pointer error comes.

Clearly the you pointer is being NULL when client side machine code is being run...so i think there should be some simple code error i am doing.

using ANET is a good option though learning it would take some time for me i guess ! any simple FPS shooter examples in ANET ( the pong one doesnt have such a scnario actually that my project has)....
