Description

Description:
Runs given statement every frame.
Arma 3
In order to keep compatibility between official and community content:
Groups:
Event Handlers

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 the 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"... 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: // Will throw an error onEachFrame { sleep 1; };
Example 5:
onEachFrame {}; // Reset event
