Description

Description:

Runs given statement every frame.

In order to keep compatibility between official and community content:

• Since Arma 3 v1.57 a stackable version of this EH is available: EachFrame Mission Event Handler
• Before that, the scripted version of the event handler should be used instead (using BIS_fnc_addStackedEventHandler and BIS_fnc_removeStackedEventHandler).

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
