Example 4 with ICommand

use of net.minecraft.command.ICommand in project watson by totemo.

the class ClientCommandManager method executeCommand.

// --------------------------------------------------------------------------
/**
   * @see net.minecraft.src.ICommandManager#executeCommand(net.minecraft.src.ICommandSender,
   *      java.lang.String)
   * 
   *      The JavaDocs for the interface don't currently describe the exact
   *      meaning of the return value. Looking at the code for
   *      {@link net.minecraft.src.CommandHandler} it contains a loop that
   *      applies a command for all players who match a particular name pattern.
   *      The returned value is the number of times that the command was
   *      successfully executed by that loop. Therefore in the case of this
   *      class, it returns 1 on success and 0 on error.
