kingofnuthin1980 51 Posted December 19, 2021 [RELEASE] Script to para jump and land with your squad in formation When using steerable parachutes, my squad never followed me. They were spinning around, hanging in their parachutes, and they were landing wherever they want. I got tired to catch up with my squad after every jump, so I wrote this script. WHAT IT DOES: If you go into freefall, your squad will drop out of the aircraft. When not looking at your squad, it gets repositioned behind you. In freefall and when they are in their parachutes. Your squad opens the parachute when you do, or when they reach a height between 100 and 75 meters. Your squad should land close to you. To make the units not spin around in their parachutes, the simulation of the parachute is disabled. THE SCRIPTS: Add this eventhandler for your player unit, to check for freefall animation: Spoiler //--- auto parachute player addEventHandler ["AnimStateChanged", { params ["_unit", "_anim"]; //--- check if unit is in freefall, if auto parachute is enabled, and freefall variable inactive if ("freefall" in (toLower _anim) && (AIM_VAR_GAMEPLAY_SETTINGS select 17) && !(_unit getVariable ["#freefall", FALSE])) then { //--- set freefall variable active to disable this eventhandler _unit setVariable ["#freefall", TRUE]; //--- init para drop _null = [_unit] call AIM_fnc_paraDropInit; }; //--- check if unit landed, is not in freefall, and freefall variable active if (isTouchingGround _unit || !("freefall" in (toLower _anim)) && (_unit getVariable ["#freefall", FALSE])) then { //--- set freefall variable inactive to re-enable this eventhandler _unit setVariable ["#freefall", FALSE]; }; }]; AIM_fnc_paraDropInit (this adds the action to open your parachute, handles your squad exit out of the aircraft, and initializes the formation) Spoiler /* ---------------------------------------------------------------------------- Author: ai-mods Description: adds action to open parachute to player and handles the squad for the para jump Parameter(s): 0 - OBJECT: unit (player) Returns: BOOLEAN Example: _null = [player] call AIM_fnc_paraDropInit;

stburr91 995 Posted December 20, 2021 First let me say nice job on the script, it must have taken quite a bit of time to create, so thanks for the effort. However, I solved the same problem with 3 lines of code, by simply attaching the AI to the player after jumping out of the plane, and putting them into the free fall animation, then detaching them at 120 meter above the ground, where they open their chutes on their own, and land within 50 meters of the player. This worked perfectly in the mission that I used it in. 2 Share this post Link to post Share on other sites

This worked perfectly in the mission that I used it in. I did that, too. But I didn't like, when the units are glued to their position behind me, when turning around while looking at them in third person. If you want to solve that with an attach code, I bet you'll need more than three lines, too. 😉 Edit: Not saying my approach is perfect, because it's not. It's just a matter of taste on how it plays out in the end. 2 Share this post Link to post Share on other sites
