Issue when acessing a variable from another class

[SellDemApplez]

Hello! As the title says, whenever I try to access a variable from another class, the error is thrown saying that it "is reading at address zero". here is the code, am I doing something wrong?

The Class I am trying to access the variable

Code: Select all

class MyStandaloneGameHUD : BaseStatusBar

{
	HUDFont mHUDFont;

	SendirPlayer pmo;
	ShieldItem shield;
	bool shieldStatus;
	override void Init(void)

	{
		Super.Init();
		SetSize(0, 320, 200);
		Font fnt = SmallFont;
		mHUDFont = HUDFont.Create(fnt, fnt.GetCharWidth("0"), Mono_CellLeft, 1, 1);
		Self.shieldStatus = shield.hasUsedShield;
	}



	override void Draw(int state, double TicFrac)

	{
		if (CPlayer && CPlayer.mo)
		{
			pmo = SendirPlayer(CPlayer.mo);
		}
		
		BaseStatusBar.Draw(state, TicFrac);
		if (state == HUD_StatusBar || state == HUD_Fullscreen)
		{
			BeginHUD(forcescaled: true);
			DrawHUD();
		}
	}
	void DrawHUD()
	{
		
		//DrawBar("barfull","barblank",pmo.player.health,100,(99, -20),0,SHADER_VERT,
			//DI_ITEM_CENTER | DI_SCREEN_LEFT_BOTTOM );
		DrawString(mHUDFont, StringTable.Localize("$TXT_HUD_HEALTH") .. FormatNumber(pmo.player.health, 3), (22, -30));
		DrawString(mHUDFont, StringTable.Localize("RAGE:") .. FormatNumber(pmo.rage, 3), (22, -20));
		DrawString(mHUDFont, StringTable.Localize("Arcane Shells:").. pmo.CountInv("Shell") , (260, -20)); //.. CheckInventory("Shell")
		DrawString(mHUDFont, StringTable.Localize("Shield:").. getShieldStatus() , (260, -20)); 
	}
	String getShieldStatus()
	{
	if (!shieldStatus) return "Ready!";
	else return "Not Ready";
	
	}

}

The class that has said variable

Code: Select all

class ShieldItem : CustomInventory {

	bool hasUsedShield;
	property hasUsedShield : hasUsedShield;

Default {
	Inventory.PickupMessage "Picked up the Shield!";
	Inventory.Amount 1;
	Inventory.DefMaxAmount 1;
	
	Self.hasUsedShield false;
	
}


}
