- player (1-32): id of a player (or 0 for all)
- id (0-199): internal text id
- duration (ms): alpha fade/transition effect in milliseconds
- alpha (0.0-1.0): new alpha value
Lets a HUD text (specified with id) change its alpha value. The transition will be smooth and will take the given time (duration).
You can let this effect be visible for all players (player=0) or to a certain player only (player=id of this player).
alpha must be a value between 0.0 (invisible) and 1.0 (fully opaque).
