Hello,

First of all, this is what i would like to accomplish:

• Retrive keyvalue pairs from an entity directly

The way i've been handling keyvalues in the past is by hooking FM_KeyValue and storing keyvalue data as they are being set by the engine.

Now, in a new project for Sven Co-op, there is a loophole where keyvalue data can be changed through certain entities native to Sven Co-op. Such as:

• trigger_changevalue - https://sites.google.com/site/svenma...er_changevalue
• trigger_copyvalue - https://sites.google.com/site/svenma...gger_copyvalue

During my testing, triggering these entities can successfully change keyvalues of other entities without the FM_KeyValue forward being triggered.
Should such an entity be triggered i become blind to the fact that the keyvalue data of its target is different from when i last retrieved it; as my local cache of the target entity is now different from reality.

Now i am asking for your help. Is there another way of retrieving keyvalues, maybe directly from the engine?
Could it be possible to hook the function these entites use to change keyvalue data?

Even getting just the value when you already know the key would be somewhat useful.

Thank you for your time.

Does this works?

I wrongfully specified i hooked FM_SetKeyValue in my original post, which has been updated.

PHP Code:

From kve.sma

register_forward(FM_KeyValue, "on_key_value"); 


It uses the same forward - FM_KeyValue. I doubt it will be of much help.

That hook is executed when the game engine calls DispatchKeyValue() in mod DLL. That happens for entities which are read from BSP. These 2 entities probably don't use the same function to change keyvalues, they most likely call ::KeyValue() virtual function on the targeted entity.
So, you would probably have to hook Ham_KeyValue for all entities, or use, say Orpheu, to hook the function which these 2 entities use.

Thank you for your input Klippy, and i do believe you are correct.
I've succesfully hooked ::Keyvalue() on a func_door as a test and when changing, for example, the wait key everything goes smoothly.
However, some other keys such as speed or angles does seemingly not use the func_door's ::Keyvalue() function. Any reason why some keys would get set differently?
