Statement is run every frame.

In order to keep compatability between official and community content the functions BIS_fnc_addStackedEventHandler and BIS_fnc_removeStackedEventHandler should be used instead.


onEachFrame statement
statement: Code
Return Value:


Example 1:
onEachFrame { hintSilent str position player; }; //Hints position every frame
Example 2:
Private variables defined outside of onEachFrame scope are not inherited: _myvar = "bob"; myvar = "bill"; onEachFrame { hintSilent str [_myvar, myvar] }; //Result: [any,"bill"]
Example 3:
Only one onEachFrame loop can exist at any time: onEachFrame { player sideChat "first"; }; onEachFrame { player sideChat "second"; }; //Result: "second","second","second"..."second" Note how "first" never gets shown even though it precedes "second". This is because script thread is executing within the same frame and first onEachFrame is overwritten before it has a chance to execute its statement.
Example 4:
Script suspension is not permitted within onEachFrame scope: onEachFrame { sleep 1 }; //ERROR!!!

If you need a stackable onEachFrame event, use mission event handler "Draw3D": addMissionEventHandler ["Draw3D", {...code to run each frame...}]; It is not a full substitute to onEachFrame and "Draw3D" will stop executing on Alt+Tab and doesn't work on hasInterface => false clients, such as dedicated server.
