Fading a Sprite in and out by distance? (solved)

[Krull0r]

Hello


Is it possible to make a Sprite fading in and out depending on its VisibilityHeight, -Radius and ScaleGlow?


I'm using a small hand symbol that show the player ingame where he can use the grab key. The Sprite has a VisibilityHeight and Radius of 256.
Actually the Sprite appears and disappears instant after entering or leaving the "VisibiltyZone".


For example when the player is 256 units away from the sprite it should be invisible and if he comes closer to the sprite it should become more visible and maybe a max VisibiltyZone would be nice. ( 256 Units away, Invisible - Fade to 96 Units -> there it should be 100 % Visible )



Is there any possibility to achieve something like that?

That's a pretty easy effect to pull off. Just change either the transparency or drawscale to be a factor of the distance to the player. Since you are drawing this on the player's HUD you'll have full control with no need of input from the server.

I'm not a big fan of altering it to be "see-through", I think the better effect is to make the hand larger as you get near and maybe add color when it's usable. There's just too many maps with fog, smoke, weird background alpha channels that could interfere with your effect, etc.

Oh okay. I don't really have any Idea how to do this


The "Hand" sprite is an actor placed above carcasses, consoles, buttons and levers.
And the sprite texture is a decent pulsing material sequence so the player will notice:"oh there is something blinking. I should check this out".

The Hand is only planed for my project. So there will be no trouble with other maps.
