[General] IsUnitVisible

[Chaosy]

Hello, I want to display a floating text if a certain unit is visible, with other words if the unit is within camera range.

My only idea was to create a temp region and calculate the size of it depending on the current camera settings. But that seems both buggy and advanced, any other ideas?

edit1: a second idea would be to calculate the distance between the unit and the center of the camera, however this wont work since my screen is not a square.

not everything that is in the camera's field of view is on the screen, consider fog of war.

If this is single player you shouldnt have much problem, if this is multiplayer, it may be a bit of a problem to avoid desyncs

Just display a floating text if that unit is not in fog of war for player.

If his camera is not looking there he won't see text anyway???

you can move the texttag to certain position at the rect of the camera's field of view, which will make it always visible + Im pretty sure you can see floating text even through fog of war

The text is following the screen atm, but that's rather pointless if you can't see the unit that the text is "attached" to.

I think checking if the unit is visible for player X isn't good enough in my case, sorry.

You need a combination of IsUnitVisible for the local player and your suggestion on post #1, which is merely this. Just add an extra condition to see whether the unit is in the defined region.

The former will allow you to see if the unit, given that it is within the local player's camera target region, is still visible to the player (e.g. has been hidden with the action Unit - Hide unit or is invisible through spells).

I have decided to just display it if the unit is selected instead, it works just as good in most cases and is way easier to use. (+4) rep to everyone who replied.

edit: ceday, I couldn't give you rep unless I spread, sorry!
