Better way to check if a player is now wearing a new uniform?

nebulazerz · December 16, 2013

I have easter eggs hidden in my game mode im working on, one is a power suit. Right now I have it checking to see if the player picked it up with an inventory closed event handler but I dont always give it to the player by having them pick it up off the ground, any suggestions for a better method to check than this?

player addEventHandler ["InventoryClosed", {
		player removeAllEventHandlers "InventoryClosed";
		_powerSuit = "U_B_Soldier_VR";
		if (uniform player isequalto _powerSuit) then {
		[ [], "fnc_bluSuitPowers", player ] call BIS_fnc_MP;
	};
}];

[
	"checkEquippedUniform",
	"onEachFrame",
	{
		if (uniform (_this select 0) isEqualTo "U_B_Soldier_VR") then
		{
			[ [], "fnc_bluSuitPowers", player ] call BIS_fnc_MP;
		};
	},
	[player]
] call BIS_fnc_addStackedEventHandler;

oh, thats pretty cool. a stacked event handler. This does work all though, im using this to start up holdaction "skils" and this is repeatedly adding them over and over. is there any way to stop that from happening but still have it check all of the time? remove the event handlers every time? Could this hurt performance because its checking so often or is it easy enough for the game to do that it does not effect it?

Edit: like this its hurting performance pretty bad too.

You could add a variable to the unit that would be true if it has powers and prevent the handler from adding them again by

_unit setVariable ["powers", true, true]; // the last true is to broadcast it in MP

I think your original solution is better

player addEventHandler ["InventoryClosed", {
        _powerSuit = "U_B_Soldier_VR";
        if (uniform player isequalto _powerSuit) then {
              if ( !(player getVariable ["powers", false]) ) then { [ [], "fnc_bluSuitPowers", player ] call BIS_fnc_MP; };
              player setVariable ["powers", true, true];
        } else {
              player setVariable ["powers", false, true];
        };
}];

That solution only works if the player picks it up and equips it, but the OP stated that is not always the case (implies that the uniform could be applied directly to the player via script).

onEachFrame in this case shouldn't cause too much of a performance impact, unless you are adding a whole bunch of onEachFrame stacked event handlers, which is probably the issue here, so try the following, hopefully it works better, if it doesn't I'll need to see where you are actually using and putting the code.

if !(player getVariable ["bluSuitPowers_eh",false]) then
{
	[
		"checkEquippedUniform",
		"onEachFrame",
		{
			params ["_unit"];
			if (uniform _unit isEqualTo "U_B_Soldier_VR") then
			{
				[ [], "fnc_bluSuitPowers", _unit ] call BIS_fnc_MP;
			}
			else
			{
				//remove suit powers
			};
		},
		[player]
	] call BIS_fnc_addStackedEventHandler;
	player setVariable ["bluSuitPowers_eh",true];
};

I see we've had the same idea, jshock, although I forgot to remove the powers. Anyway, if the suit is added with a script then the powers can be activated with a script, too. No need to check each frame unless it wouldn't work with virtual arsenal and the OP intends to use it. Still, your solution is more powerful and universal.

              player setVariable ["powers", true, true];
        } else {
              player setVariable ["powers", false, true];
        };
}];

Yes, this is working pretty nicely, Its just not removing the powers when I take the suit off for some reason, isnt that what the powers set variable should be doing in the first place. Am I doing this wrong, this is how its set up.

when player is given uniform if forceadded

player forceAddUniform "U_B_Soldier_VR";
			[ [], "fnc_bluSuitPowers", player ] call BIS_fnc_MP;
			player setVariable ["powers", true, true];

player addEventHandler ["InventoryClosed", {
        _powerSuit = "U_B_Soldier_VR";
        if (uniform player isequalto _powerSuit) then {
              if ( !(player getVariable ["powers", false]) ) then { [ [], "fnc_bluSuitPowers", player ] call BIS_fnc_MP; };
              player setVariable ["powers", true, true];
        } else {
              player setVariable ["powers", false, true];
			  
		};
}];

This, strangely is still spawning the abilities an infinite amount of times, heres the suit powers function so you can see what its calling

Realized my stupid mistake (tired as hell atm), try this:

if !(player getVariable ["bluSuitPowers_eh",false]) then
{
	[
		"checkEquippedUniform",
		"onEachFrame",
		{
			params ["_unit"];
			if (uniform _unit isEqualTo "U_B_Soldier_VR") then 
			{
				if ( !(_unit getVariable ["powers", false]) ) then 
				{ 
					[ [], "fnc_bluSuitPowers", _unit ] call BIS_fnc_MP; 
				};
                                _unit setVariable ["powers", true];
			} 
                        else 
			{
                                _unit setVariable ["powers", false];

		},

		},

	player setVariable ["bluSuitPowers_eh",true];
};

that works much better now, no performance hit and its giving the right amount of abilities. The powers are still there when I take the suit off though. Do I need to add a removeAction to the eventhandler in the else portion to have it work like that?

Also, just figured out how to make lightning strike wherever you are looking figured I would share so you guys can have some fun with it because its funny haha :)

private ["_strikeTarget","_dummy"];
_strikeTarget = cursorObject;
_strikeLoc =  (getPos _strikeTarget);
if (_strikeLoc isequalto [0,0,0]) then {
hint "NO TARGET";
}else{

[_strikeTarget,nil,true] call BIS_fnc_moduleLightning;

hint "";
	};

You need to remove all the actions that your fnc_bluSuitPowers adds add put a call to that above the _unit setVariable ["powers", false]; line.

nebulazerz · December 16, 2013

You need to remove all the actions that your fnc_bluSuitPowers adds add put a call to that above the _unit setVariable ["powers", false]; line.

Is there a way to setVariable an action and use that to remove it? Sequentially removing actions is not going to work in this case. if I start the player with 2 actions then this will work the first time without removing the actions and only removing the powers, but if I take off the suit a second time after picking it up, the powers are still there (probably because they are not the same sequential actions.) removeAllActions Player; would work but it removes the 2 actions that are added at mission load and I might have people start with a few default skills that can be leveled up. Nevermind, ill put the actions that I want loaded all of the time in a function and call it both times, that will fix it.

if !(player getVariable ["bluSuitPowers_eh",false]) then
{
	[
		"checkEquippedUniform",
		"onEachFrame",
		{
			params ["_unit"];
			if (uniform _unit isEqualTo "U_B_Soldier_VR") then 
			{
				if ( !(_unit getVariable ["powers", false]) ) then 
				{ 
					[ [], "fnc_bluSuitPowers", _unit ] call BIS_fnc_MP; 
				};
                                _unit setVariable ["powers", true];
			} 
                        else 
			{
								
								player removeAction 2;
								player removeAction 3;
								player removeAction 4;
								player removeAction 5;
                                _unit setVariable ["powers", false];
			};
		},
		[player]
	] call BIS_fnc_addStackedEventHandler;
	player setVariable ["bluSuitPowers_eh",true];
};

hmm, I have been messing with it quite a bit and I cant seem to get it to remove the powers properly when the suit is off, I have tried a few things like this. It will remove the default abilities if the suit goes on but it will not remove the suit abilities if it goes to 'else' and checks for default actions. Do I have the order of lines wrong?

if !(player getVariable ["bluSuitPowers_eh",false]) then
{
	[
		"checkEquippedUniform",
		"onEachFrame",
		{
			params ["_unit"];
			if (uniform _unit isEqualTo "U_B_Soldier_VR") then 
			{
				if ( !(_unit getVariable ["powers", false]) ) then 
				{ 
					removeAllactions player;
					[ [], "fnc_bluSuitPowers", _unit ] call BIS_fnc_MP; 
				};
                                _unit setVariable ["powers", true];
			} 
                        else 
			{
				if ( !(_unit getVariable ["defaultActions", false]) ) then 
				{ 
					removeAllactions player;
					[ [], "fn_defaultActions", _unit ] call BIS_fnc_MP; 
					_unit setVariable ["defaultActions", true];
				};
                                
                                _unit setVariable ["powers", false];
			};
		},
		[player]
	] call BIS_fnc_addStackedEventHandler;
	player setVariable ["bluSuitPowers_eh",true];
};

Edit: Also, why does nothing show up after respawning even if I put this in my onPlayerRespawn.sqf and how can I fix that?

nebulazerz · December 16, 2013

I figured it out! Turns out you can save actions to a variable and removeAction the variable... would be nice if this page even mentions that a tiny bit, i tried it out of curiosity and it works

Edit: Well, seems they do mention it here at the bottom, but i was looking to remove actions not add them so it kinda slipped my mind to check the addaction page especially since im using holdaction

Edit: I have a new issue, it seems that this eventhandler is not reactivating on respawn. I tried putting it in a function and in onPlayerRespawn.sqf I added [player] call fn_suitPowerEH; but that doesnt work either.

Heres what it looks like

if !(player getVariable ["bluSuitPowers_eh",false]) then
{
	[
		"checkEquippedUniform",
		"onEachFrame",
		{
			params ["_unit"];
			if (uniform _unit isEqualTo "U_B_Soldier_VR") then 
			{
				if ( !(_unit getVariable ["powers", false]) ) then 
				{ 
					
					[ [], "fnc_bluSuitPowers", _unit ] call BIS_fnc_MP; 
				};
                                _unit setVariable ["powers", true];
			} 
                        else 
			{
				 
					_skillA = player getVariable ["skillA",-1];
					_skillB = player getVariable ["skillB",-1];
					_skillC = player getVariable ["skillC",-1];
					_skillD = player getVariable ["skillD",-1];
					player removeAction _skillA;
					player removeAction _skillB;
					player removeAction _skillC;
					player removeAction _skillD;
						
                    _unit setVariable ["powers", false];
			};

Better way to check if a player is now wearing a new uniform?
