despair Setting a slider's position using the onLoad event

[Neviothr 102]

I have this slider:

class RscSlider;

class nevDebugMenu {
	duration = 99999;
	idd = 80000;
	onLoad = "call NEV_fnc_onLoad";
	class controls {
		// A slider to change the overcast value
		class overcastSlider: RscSlider {
		    idc = 80003;
		   	x = "SafeZoneX + (960 / 1920) * SafeZoneW";
			y = "SafeZoneY + (285 / 1080) * SafeZoneH";
			w = "(200 / 1920) * SafeZoneW";
			h = "(30 / 1080) * SafeZoneH";
		    type = CT_SLIDER;
		    style = SL_HORZ;
		    tooltip = "Change overcast";
		};
	};
};

I want to set it to a certain position whenever the dialog is loaded. This is how NEV_fnc_onLoad looks:

NEV_fnc_onLoad = {
	_dialog = findDisplay 80000;
	_slider = _dialog displayCtrl 80003;
	sliderSetRange [80003, 0, 10];
	sliderSetPosition [80003, 5];
}

Unfortunately, it doesn't seem to work. The slider appears fine, is moveable, but when the dialog is loaded, it's in the leftmost position (0), while in theory, it needs to be in the middle of the slider (position 5). Does anyone know how to fix/achieve this?

Thanks.

Hi

do you have error reporting on?

the NEV_fnc_onLoad  is missing ";" from the end "}"

Try something like this:

 

class RscSlider;

class nevDebugMenu {
	duration = 99999;
	idd = 80000;
	onLoad = "_nul = [""onLoad"",this] call NEV_fnc_nevDebugMenu;"; // changed expression and function call
	class controls {
		// A slider to change the overcast value (look at RscXSlider - more pretty version of RscSlider)
		class overcastSlider: RscSlider {
		    idc = 80003;
		    x = "SafeZoneX + (960 / 1920) * SafeZoneW";
		    y = "SafeZoneY + (285 / 1080) * SafeZoneH";
		    w = "(200 / 1920) * SafeZoneW";
		    h = "(30 / 1080) * SafeZoneH";
		    type = CT_SLIDER;
		    style = SL_HORZ;
		    tooltip = "Change overcast";
                    onSliderPosChanged = "_nul = [""sliderMoved"",this] call NEV_fnc_nevDebugMenu;"; // added onSliderPosChanged event handler
		};
	};
};

NEV_fnc_nevDebugMenu:

 

Just as a heads up, the overcast values range from 0 to 1, as such, I have ammended your sliders range values. It is better to describe functions in the CfgFunctions and let the game handle this for you. From preference I try to bundle the display script/handler functions in to one program and switch between different modes (best to only use this for up to 10 different modes).

// check if calling machine has interface
if !(hasInterface) exitWith {};

_this params [
	["_mode","",[""]],
	["_params",[],[[]]]
];

switch (_mode) do {
	//-------------------------------------------------------
	// onload - executed when interface load handler is fired
	case "onLoad" : { 
		_params params [
			["_display",displayNull,[displayNull]]
		];

		// check if display was passed
		if (isNull _display) exitWith {};

		// set slider position
		_sliderCtrl = _display displayCtrl 80003;
		_sliderCtrl sliderSetRange [0,1];
		_sliderCtrl sliderSetPos 0.5;
	};
	//-------------------------------------------------------
	// sliderMoved - executed when slider position is changed
	case "sliderMoved" : {
		_params params [
			["_sliderCtrl",controlNull,[controlNull]],
			["_sliderPos",0,[0]]
		];

		// check control was passed
		if (isNull _sliderCtrl) exitWith {};

		// get display to update other controls
		_display = ctrlParent _sliderCtrl;

		// set the overcast from slider value
		0 setOvercast _sliderPos;
		forceWeatherChange; // submits the change (best to have this on a submit button as it needs to sync to all clients)
	};
	//-------------------------------------------------------
	// default case - displays error message for invalid mode
	default {
		_nul = ["NEV_fnc_debugMenu: '_mode' was invalid!"] call BIS_fnc_error;
	};
};
          

(I haven't tested this code)

 

Hope this helps point you in the right direction :)

If after } there are no more statements or another } it is not a probem

Thank you for your help, but unfortunately, @bull_a I wasn't able to get your code to work properly for me. And having this been the 6th or 7th time I've tried creating weather sliders - I've decided to settle for a much dumber, and inefficient solution.

debug_menu.hpp:

class RscSlider;
class RscButton;

class nevDebugMenu {
	duration = 99999;
	idd = 80000;
	onLoad = "call NEV_fnc_onLoad";
	class controls {
		// A slider to change the overcast value
		class overcastSlider: RscSlider {
		    idc = 80003;
		   	x = "SafeZoneX + (960 / 1920) * SafeZoneW";
			y = "SafeZoneY + (285 / 1080) * SafeZoneH";
			w = "(200 / 1920) * SafeZoneW";
			h = "(30 / 1080) * SafeZoneH";
		    type = CT_SLIDER;
		    style = SL_HORZ;
		    tooltip = "Change overcast";
		};

		// A slider to change the lightning value
		class lightningSlider: RscSlider {
		    idc = 80004;
		   	x = "SafeZoneX + (960 / 1920) * SafeZoneW";
			y = "SafeZoneY + (330 / 1080) * SafeZoneH";
			w = "(200 / 1920) * SafeZoneW";
			h = "(30 / 1080) * SafeZoneH";
		    type = CT_SLIDER;
		    style = SL_HORZ;
		    tooltip = "Change lightning";

		// A slider to change the fog's value
		class fogValueSlider: RscSlider {
