Texture in mouselook?

[Prometheus Daines]

Anyone know a simple way to display a texture ONLY in mouselook via UUID (such as a crosshair HUD). Pulling my hair trying to find reference material.

The way that immediately springs to mind is to have the hud keep on testing for AGENT_MOUSELOOK with llGetAgentInfo and switch its visibility accordingly.

The obvious disadvantage to that is that you'll need to run quite a fast timer.   If you're using it with a weapon, though, you might well be needing to have the weapon know if you're in mouselook (perhaps so you can go into an appropriate animation), in which case the weapon could tell the hud when to hide and show itself, using llRegionSayTo.
