    Trouble Displaying Image

    Reply Quote
    I'm writing  basic 2D program. Problem is I put some buttons on a page and only one will display. If I remove the one that does display the other will show.

     I had some mouse over methods that changed the image color but i have commented them out thinking that was the issue but I still get the same end result.

    Here is my code.

    MenuScreen.cs

    using System; 
    using System.Collections.Generic; 
    using System.Text; 
    using Microsoft.Xna.Framework; 
    using Microsoft.Xna.Framework.Graphics; 
    using System.Collections; 
     
    namespace BugColony 
    { 
        public enum Buttons 
        { 
            New, 
            Exit 
        } 
        class MenuScreen : BaseScreen 
        { 
            public ArrayList MyButtons = new ArrayList(); 
            ExitButton exit = new ExitButton(new Vector2((800 / 2) - (Images.ExitButton.Width / 2), 500)); 
            NewGameButton newgame = new NewGameButton(new Vector2((800 / 2) - (Images.ExitButton.Width / 2), 370)); 
     
            public ArrayList Bugs = new ArrayList(); 
            public void CreateBugs() 
            { 
                for (int i = 0; i < 10; i++) 
                { 
                    MenuBug bug = new MenuBug(); 
                    Bugs.Add(bug); 
                } 
            } 
            public void CreateButtons() 
            { 
                /*ExitButton exit = new ExitButton(new Vector2((800 / 2) - (Images.ExitButton.Width / 2), 500));
                MyButtons.Add(exit);
                NewGameButton newgame = new NewGameButton(new Vector2((800 / 2) - (Images.ExitButton.Width / 2), 370));
                MyButtons.Add(newgame);*/ 
            } 
            public MenuScreen() : base() 
            { 
                CreateBugs(); 
     
                //CreateButtons(); 
            } 
     
            public override void Draw(Game1 game) 
            { 
                //draw background 
                game.spriteBatch.Draw(Images.MenuBG, new Vector2(0, 0), Color.White); 
     
                //draw bugs 
                foreach (MenuBug bug in Bugs) 
                { 
                    bug.Draw(game); 
                } 
                //draw buttons 
                /*string rects = "";
                for (int i = 0; i < MyButtons.Count;i++ )
                {
                    BaseButton button = MyButtons[i] as BaseButton;
                    button.ShowImage(game);
                    rects = "   Rect: " + button.Area.ToString();
                }*/ 
                exit.ShowImage(game); 
                //newgame.ShowImage(game); 
     
                //Debug *** 
                game.Window.Title = exit.Area.ToString(); 
     
                base.Draw(game);

    Problem solved. For some reason I set the Primary Image to static and that was causing the issue.
