devWaleed, you are talking about parameters.
2!0 means that 2nd parameter must not be equal to 2,
2&#Game_w means that 2nd parameter must contain
#Game_w string
1>0 means that 1st parameter must be greater than 0.
When all conditions for event are met then plugin calls specified function, for example,
Event_RoundRestart.
More info about parameters for each event is available
here.
For example, Damage event with filter "2!0", "3=0", "4!0":
- damage to player must not be equal to 0
- it is DMG_GENERIC damage type (more info in hlsdk_const.inc)
- origin by X coordinate of damage inflictor must not be equal to 0
