This function will check if an element is on the screen. Elements behind objects but still in the camera view count as being on screen.

This function is particularly useful for detecting if dynamic objects are in "destroyed" state. Destroyed objects will return false.

Syntax

bool isElementOnScreen ( element theElement )

OOP Syntax Help! I don't understand this!

Method: element:isOnScreen(...)
Variable: .onScreen

Required Arguments

  • theElement: The element of which you wish to check wether it's being rendered on screen.

Returns

Returns true if element is on screen, false if not.

Issues

Issue ID Description
#3510 isElementOnScreen doesn't work for markers

Example

This function will check if you can see your killer when you die. 

function player_Wasted ( killer, weapon, bodypart )
    -- if there even was a killer and the killer isn't the killed player itself
    if ( killer ) and ( killer ~= source ) then
        -- there was a killer
        if ( isElementOnScreen ( killer ) ) then
            -- the killer was on screen
            outputChatBox ( "You can still see your killer!", 255, 0, 0 )
        else
            -- the killer was not on screen
            outputChatBox ( "You can not see your killer!", 255, 0, 0 )
        end
    end
end
-- call player_Wasted when only the local player dies
addEventHandler ( "onClientPlayerWasted", localPlayer, player_Wasted )
