"example: i load a mesh with children objects, one children is invisible and the others no, i need get the entity invisible, but what is it?"
Are you talking about the transparency (alpha) state of the entity? If so, I'm not aware of any command that will tell you this. You need to store the transparency state in a variable and set the state using the value in that variable. Then you can simply read the variable to find the transparency state.
If you're talking about visibility picking using the pick commands, then make sure you have the pick mode of your entities set correctly by using 'EntityPickMode'. Remember that you'll also need to set the pick mode of any entities that you want to obscure (block) the picking of your entities, including your game arena meshes.
