"Changes the crosshair that is used when focusing an entity."

[Scupp]

How can I use this script or am I understood it properly?
I have broken ladders on my custom map and I want that whenever I focus/watch on those ladders at close range there will be different crosshair and text on the screen. I think I can make the text but how can I change that crosshair? I don't know is this for that purpose or am I just using it wrong:


void SetEntityCustomFocusCrossHair(string& asName, string& asCrossHair);
