<function name="StartCommand" parent="GM" type="hook"> <ishook>yes</ishook> <description> Allows you to change the players inputs before they are processed by the server. This is basically a shared version of <page>GM:CreateMove</page>. <note>This function is also called for bots, making it the best solution to control them so far</note> <note>This hook is predicted, but not by usual means, this hook is called when a <page>CUserCmd</page> is generated on the client, and on the server when it is received, so it is necessary for this hook to be called clientside even on singleplayer</note> </description> <realm>Shared</realm> <predicted>Yes</predicted> <hidepredictionwarning>Disable automatic prediction warning</hidepredictionwarning> <args> <arg name="ply" type="Player">The player</arg> <arg name="ucmd" type="CUserCmd">The usercommand</arg> </args> </function> <example> <description> Example of how you'd control a bot using this hook.
