I'v been searching this for hours but there are only some references.

PHP Code:

#define IN_ATTACK     (1 << 0)
#define IN_JUMP       (1 << 1)
#define IN_DUCK       (1 << 2)
#define IN_FORWARD    (1 << 3)
#define IN_BACK       (1 << 4)
#define IN_USE        (1 << 5)
#define IN_CANCEL     (1 << 6)
...
#define FL_ONGROUND   (1 << 0) on the ground
#define FL_DUCKING    (1 << 1) fully crouched
#define FL_WATERJUMP  (1 << 2) jumping out of water
#define FL_ONTRAIN    (1 << 3) _controlling_ a train
#define FL_INRAIN     (1 << 4) standing in rain
#define FL_FROZEN     (1 << 5) frozen
#define FL_ATCONTROLS (1 << 6) can't move
#define FL_CLIENT     (1 << 7) player
#define FL_FAKECLIENT (1 << 8) fake client
... 


PHP Code:

SetEntProp(client, Prop_Send, "m_fFlags", 8); 


How is the 8 calculated according to the flags table? Can I directly use FL_*** instead of a calculated number?

Could someone please give me some examples on how to set/remove certain flags? Thanks!

http://web2.0calc.com/ - Punch in (1 << 0) and you'll receive 1, (1 << 1) to receive 2, (1 << 2) to receive 4, (1 << 3) to receive 8, etc. So 8 == FL_ONTRAIN. You can use 8, (1 << 3), or FL_ONTRAIN, they all mean the same.

PHP Code:

new iFlags = GetEntProp(client, Prop_Send, "m_fFlags");
iFlags &= ~FL_ONTRAIN; //Remove flag
if(iFlags & FL_DUCKING) //possess flag
  iFlags |= FL_ONGROUND; //Add Flag.
SetEntProp(client, Prop_Send, m_fFlags, iFlags);

ahaa...big thanks thetwistedpanda

That calculator is good, and your simple explanation and example are really helpful.

I'm hoping that SourceMod does some twiddling for these values, because the versions in entity_prop_stocks.inc match the single player values in Source SDK 2013's const.h and not the multiplayer values, which have FL_ANIMDUCKING between FL_DUCKING and FL_WATERJUMP:

#define FL_ANIMDUCKING            (1<<2)    // Player flag -- Player is in the process of crouching or uncrouching but could be in transition
// examples:                                   Fully ducked:  FL_DUCKING &  FL_ANIMDUCKING
//           Previously fully ducked, unducking in progress:  FL_DUCKING & !FL_ANIMDUCKING
//                                           Fully unducked: !FL_DUCKING & !FL_ANIMDUCKING
//           Previously fully unducked, ducking in progress: !FL_DUCKING &  FL_ANIMDUCKING

Given that this file is essentially from the source code used by HL2:DM, DoD:S, CS:S, and TF2...

It does. GetEntityFlags was changed from a stock to a native many versions ago and handles different internal flag values per game.
