Nice... Moved posts. Though I do think that "How to block PlayerUse ?" would fit a bit more than "How to hook PlayerUse ?" for thread name. =P

And the reason why I am suggesting to use PlayerPreThink rather than PlayerPostThink is because if using Post, than you will have IN_USE set in pev_oldbuttons, at functions where it shouldn't be there. In other words if you are holding IN_USE and block it at every PlayerPostThink, than during the time when you are holding your use key, pev_oldbuttons will have IN_USE in them. That won't necessary lead to some engine glitches (though it might - here I'm just guessing), but it can cause problems with other plugins what detect when you release USE key (this once I can say for sure - don't know if such a plugin exists, but it wont he hard to create one).
