If you need a stackable [[onEachFrame]] event, use mission event handler "[[Arma_3:_Event_Handlers#Draw3D|Draw3D]]":
<code>[[addMissionEventHandler]] ["[[Arma_3:_Event_Handlers#Draw3D|Draw3D]]", {...code to run each frame...}];</code>
It is not a full substitute to [[onEachFrame]] as "[[Arma_3:_Event_Handlers#Draw3D|Draw3D]]" will stop executing on Alt+Tab and doesn't work on [[hasInterface]] <nowiki>=</nowiki>&gt; [[false]] clients, such as dedicated server.

Description

Description:
Runs given statement every frame.
ⓘ
Since Arma 3 v1.57 a stackable version of this EH is available: EachFrame
Template:Feature arma3
Groups:
Uncategorised

Syntax

Syntax:
onEachFrame statement
Parameters:
statement: String or Code
Return Value:
Nothing

Examples

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!!!
