2 Model for each Optikmode

[frankyman 10]

Hello folks,
I'm having real problems with a project.
Unfortunately I have to admit that I am a real noob when it comes to scripting.
The project is an xm7 with the xm157 visor.
For the aiming optics I use “xm157_info_type” from the Ace.
Unfortunately this is not very good when it comes to close combat.
So my idea was to convert the optics into a 3d sight. Like in the RHS MOD ( big fan ).
but the conversion was so extensive that it is now necessary to change the model, if you are in the CameraView==“GUNNER”, and in the correct OpticsMode 0= “DOT” the complete model must be exchanged for another.

My previous procedure is really bad.

		class XM157_hide : XM157
		{
			scope = 1;
			model = "abw\xm157\XM157_un";
			weaponInfoType = "abw_01_xm157";
			class CBA_ScriptedOptic {};
		class OpticsModes 
						{
							class optic {};
							class RedDot {};
						};
		};
};

at the moment i would be really happy if at least the change of class “XM157” to “XM157”_hide and back again would work.
the whole thing should be solved via a function.

Ich konnte schon vor 10 Jahren, als ich nun Fahrzeuge für Arma2 gemacht habe, nicht skripten.
Die Zeit und einige gesundheitliche Probleme machten es nicht besser. deshalb schäme ich mich das skript zu posten.

		if (!isServer) then
		{
			while {true} do
			{
				disableSerialization;

				private _p = missionNamespace getVariable ["bis_fnc_moduleRemoteControl_unit", player];
				if (((primaryWeaponItems _p) select 2) isEqualTo "XM157" && cameraView isEqualTo "GUNNER" && cameraOn _p && (player getOpticsMode 0) isEqualTo "RedDot") then
				{
					_p addPrimaryWeaponItem "XM157_hide";
					}, {exitWith}

					sleep 0.5;
				};
				
				};

I am open to all ideas.
another possibility would be PIP . but when I looked at the code for it and the one from ACE, I have to admit quite honestly that it's out of my league.
Thank you for reading at least this far.
