[SOLVED] eventHandler for opening the parachute

[Fastfood4Bigfoot 0]

Hi,

 

I need help to get this running. I want to call some code on opening the parachute. I didn't found anything matching in the list: https://community.bistudio.com/wiki/Arma_3:_Event_Handlers. I even tried the GetIn-Handlers because the parachute seems to be handled as a vehicle. Any ideas?

 

Thx in advance ;)

That's not what I'm searching for. I know how to open the parachute. I want to react with a script on opening the parachute. So when the player uses the default mouse wheel menu entry "open parachute", something should happen.

animationState player == "para_pilot"

[Harzach 2505]

^^^

if (animationState player == "para_pilot") then {
    ("SmokeShell" createVehicle (position player)) attachto [(vehicle  player)];
};

You might want to tweak the offset of that smokeshell, though.

 

[Fastfood4Bigfoot 0]

Yep, that code works - but I still don't know whats the best way of checking the current state again and again.

player addEventHandler ["AnimChanged", {
    params ["player", "para_pilot"]; hint "hello";
}];

didn't worked. Shall I just use a dumb while-loop?

[Harzach 2505]

I would think the EH would be preferable, but your example is not how they work. Just spitballing, but it should be something like this I think?

player addEventHandler ["AnimChanged", { 
    if ((_this select 1) == "para_pilot") then {
        ("SmokeShell" createVehicle (position player)) attachto [(vehicle player)];
    }; 
}];

Most probably wrong, but something like that.

I've got work to do, but I'll give it a shot in the morning, unless a smarter person beats me to it.

untested

player addEventHandler ["AnimChanged",
{	
	params ["","_anim"];
	if (_anim isEqualTo "para_pilot") then
	{
		("SmokeShell" createVehicle (position player)) attachto [(vehicle  player)];
	};
}];

AnimChanged EH

 

edit: too late...

[Fastfood4Bigfoot 0]

Nope. Both don't seem to work. Best working code until now is

while {true} do {
	if (animationState player == "para_pilot") then {
    	("SmokeShell" createVehicle (position player)) attachto [(vehicle  player)];
    	};
	sleep 0.1;
};

 

[Lucullus 71]

Hmm, can´t test it yet...

What about...

player addEventHandler ["AnimChanged",
{	
	params ["","_anim"];
	hint format ["%1",_anim];
}];

...to check anim name?

Nothing happens. I don't really understand AnimChanged yet.

Use this instead:

player addEventHandler ["AnimChanged",
{	
	if (animationState player == "para_pilot") then
	{ 
		("SmokeShell" createVehicle (position player)) attachto [(vehicle  player)];
	};
}];

"para_pilot" is an action name, not an anim name.

Nope. Nothing yet.

No mods, newest version. Nothing on the screen, no hint, no error. When I'm landing and walking on the ground, it prints some letters, like "amovpercmstpsraswrfldnon".

[Larrow 2793]

Just use the action menu event handler.

inGameUISetEventHandler [ "Action", "
	params[ '', '_caller', '', '_actionName' ];
	
	if ( _actionName == 'OpenParachute' ) then {
		hint format[ '%1 opened their parachute', name _caller ];
	};
"];

Works perfectly (natch),  but I still want to figure out why the AnimChanged EH won't do anything.

[Fastfood4Bigfoot 0]

Code works for me, too, but is also creating new problems.

inGameUISetEventHandler [ "Action", " 
    params[ '', '_caller', '', '_actionName' ]; 
     
    if ( _actionName == 'OpenParachute' ) then { 
            ('SmokeShell' createVehicle (position player)) attachto [(vehicle  player)]; 
    }; 
"];

If I'm using the code above, there's the clicking sound of a thrown grenade when I open the parachute. But nothing happens... until I touch the ground - then the grenade immediately starts producing smoke. I don't know at all what's going on there, quite weird...

[Harzach 2505]

The smoke grenade is being spawned before the parachute exists, I would guess. This works:

inGameUISetEventHandler [ "Action", "
    params[ '', '_caller', '', '_actionName' ];
    
    if ( _actionName == 'OpenParachute' ) then {
        hint format[ '%1 opened their parachute', name _caller ];
        _nul = [_caller] spawn {
            _caller = _this select 0;
            sleep 3;
            ('SmokeShellRed' createVehicle (position _caller)) attachto [(vehicle _caller),[-0.4,0,1.5]];
            ('SmokeShell' createVehicle (position _caller)) attachto [(vehicle _caller),[0,0,1.5]];
            ('SmokeShellBlue' createVehicle (position _caller)) attachto [(vehicle _caller),[0.4,0,1.5]];
        };
    };
"];

[Larrow 2793]

inGameUISetEventHandler [ "Action", "
	params[ '', '_caller', '', '_actionName' ];
	
	if ( _actionName == 'OpenParachute' ) then {
		_thread = [ _caller ] spawn {
			params[ '_caller' ];

			waitUntil { vehicle _caller != _caller };
			
			_emitters = [];
			{
				_x params[ '_pos', '_color' ];
				
				//Following borrowed from BI smoke module

				[1,0.55,0.35], 0.1, 0.08*_expansion, '', '', ''];
				
				_emitter setParticleRandom [_particleLifeTime/2, [0.5*_effectSize,0.5*_effectSize,0.2*_effectSize], [0.3,0.3,0.5], 1, 0, [0,0,0,0.06], 0, 0];

Adjust particles, their position and colors to what ever you desire.

 

EDIT: Added removal of particles once the player has touch down.

@Harzach: Nice offsets for the smoke grenades, although in already saw in videos the smoke grenade to be tied to to a leg:

 

@Larrow: Nice solution, works until the landing - probably I will further improve the smoke grenade with automatically respawning smoke shells. Maybe a little bit too much smoke, thinking about tweaking the parameters.

That's what @davidoss was going for in your other topic, but of course, the problem is that we can't attachTo a unit in a parachute. Offsetting a smokeshell down to where the player's foot should be would look even worse, as the player's legs are constantly swinging and moving around, while the smokeshell would stay in the same relative position.

Late to the party, but I stumbled across this thread, so why not contribute...
I had the same challenge, in my case reacting on parachute being opened by AI units. I solved it by triple EHs, yet to figure out which ones I need and which ones I can omit:
 

driver ( somevehicle ) addEventHandler ["AnimChanged", 
	{ 
		params ["_unit","_anim"]; 
		if (animationState _unit == "para_pilot") then {
			// do something
		};
	
	}
];
driver ( somevehicle ) addEventHandler ["AnimStateChanged", 
	{ 
		params ["_unit","_anim"]; 
		if (animationState _unit == "para_pilot") then {
			// do something
		};
	
	}
];
driver ( somevehicle ) addEventHandler ["AnimDone",  
	{ 
		params ["_unit","_anim"]; 
		if (animationState _unit == "para_pilot") then {
			// do something
		};
	
	}
];

Either way, worked for me.
