| Summary | 0006062: IsUnitInView() and IsUnitVisible() return true for unsynced gadgets | ||||
| Description | The unit is invisible to me but these functions return true regardless | ||||
| Tags | No tags attached. | ||||

Unsynced gadgets have global LOS afaik: https://springrts.com/wiki/Lua:Environments |
|
|
they do, see also the discussion in #6011 |

[me] Spring.IsUnitVisible only returns whether a unit is potentially visible by the camera, and if called from a gadget (which has more access priviledges than a widget) it ignores LOS. [Doo] isn't that "Spring.IsUnitInView"? What are the differences? Is there a specfic call that returns true if a unit is curently being drawn, regardless of los? [me] Spring.IsUnitInView is a stripped-down version of Spring.IsUnitVisible (IsUnitVisible checks access rights of the Lua script calling it and takes some optional arguments, IsUnitInView does neither) "Is there a specfic call that returns true if a unit is curently being drawn, regardless of los?" no, that would not make sense because unit drawing is itself tied to LOS. [Doo] There are some cases though, aren't there? Using SetUnitAlwaysVisible, wouldn't that make a unit visible regardless of its LOS state? [me] "Using SetUnitAlwaysVisible, wouldn't that make a unit visible regardless of its LOS state?" An always-visible unit will still only be drawn if it is in view, so IsUnitInView will see it when the player does. |

okay... so no way to know if a unit is in user-los from a gadget. I've stripped the nanolaser gadget unsynced part and made it into a widget, it works |
|
|
Seems to me the issue is resolved then. |
|
|
fyi you should be able to just wrap IsUnitInLos in a CallAsTeam. |

Ah yes, see here: https://springrts.com/wiki/Lua_System |
