Description

Description:
Limit the speed of an AI-driven vehicle or AI person to given value. It has continuous effect and AI will not break through the speed limitation until one is contacted, engaged or regrouped.
Problems:
Since tkoh logo small.png1.00 and as of Arma 3 logo black.png2.14, using any negative value on a helicopter will not reset the speed limit, but will force it to fly in reverse.
Groups:
Unit ControlObject Manipulation

Syntax

Syntax:
objectName limitSpeed speed
Parameters:
objectName: Object
speed: Number - in km/h; By default, it's 2 * maxSpeed of the vehicle/unit (which is defined in config). See Example 1.
Return Value:
Nothing

Examples

Example 1:
leader player limitSpeed 5; // set to walking speed sleep 30; leader player limitSpeed (2 * getNumber(configOf leader player >> "maxSpeed")); // remove the limit
Example 2:
addMissionEventHandler ["OnEachFrame", { hintSilent format ["myVehicle's speed: %1 km/h", speed myVehicle toFixed 2] }]; sleep 5; myVehicle limitSpeed 5;
Example 3:
// it was necessary to use limitSpeed repeatedly before Arma 3 1.24 _this setVariable ["speedLimit", 50]; _this spawn { while { sleep 0.1; canMove _this } do { _this limitSpeed (_this getVariable "speedLimit"); }; }; sleep 10; _this setVariable ["speedLimit", 100]; // update the speed limit
