How to make a custom Cursor?


The trick is to add a texture that look like a mouse cursor and set its x and y values to the mouse’s state.


Variable Declarations


Texture2D myTexture;
Vector2 spritePosition = Vector2.Zero;

LoadContent Function

myTexture = Content.Load(“cursor//nicecursor”);


Update Function


spritePosition.X = Mouse.GetState().X;

spritePosition.Y = Mouse.GetState().Y;

Draw Function

spriteBatch.Draw(myTexture, new Rectangle((int)spritePosition.X, (int)spritePosition.Y, 24, 24), Color.White); 

The texture will move as Mouse moves.

How to make a custom animated-Cursor?


Its similar to static cursor with more textures displaying like an animation.


Variable Declarations


Texture2D myTexture;      

Vector2 spritePosition = Vector2.Zero;    


private int a;   


LoadContent Function



myTexture = Content.Load(“cursor//11a_1″); 

Update Function

spritePosition.X = Mouse.GetState().X;
spritePosition.Y = Mouse.GetState().Y;
a++;
if (a == 24)
{
    a = 1;
}
else
{
    myTexture = Content.Load(“cursor//11a_” + a);
}    

Draw Function

spriteBatch.Begin(SpriteSortMode.Deferred, BlendState.AlphaBlend);
spriteBatch.Draw(myTexture, new Rectangle((int)spritePosition.X, (int)spritePosition.Y, 24, 24), Color.White);
spriteBatch.End();
