Objectcaps & Entity PlayerUse
Posted: Mon Oct 05, 2026 11:26 pm
Greetings.
Idk if anyone needs this, but I did anyway.
Basically not all ents are useable, sure you can hook use on them, but it wont register when a player hits his use key on it. You can change this however by messing a bit with the function objectcaps.
What is objectcaps?
Basically objectcaps defines some basic capabilities for any given entity. The function returns a bitmask where you can use the following bits:
From the sdk:
And thus if you flip e.g. the FCAP_IMPULSE_USE bit on your return, you will be able to register a player's use on the entity. Below is an example with info_target.
