Adding the object selector tool to the HUD

In this video I finally import the HUD element that we created a week or so ago.  Originally I ran into some issues with the imported image looking pretty bad.  It turns out that when you import textures they resize to a multiple of 64, i.e. 64x64, 128x128, etc.  For a small image with a lot of subtle alpha settings to blend the edges, the resizing can really screw it up.  Once I resized it in Gimp to be 128x128, it looked much better.  So from now on, we will be making our texture sizes multiples of 64.

Using Gimp to create a HUD element

I am definitely no expert in Gimp, so please keep the laughing to a minimum!  Since I am not an artist, I really appreciate the way programs like Gimp can make it easy to apply 3D effects like emboss.  In this video I create a basic image that I'm going to import as a texture and then put in the HUD of the game.  This will be the control to handle the rotation of movable objects.

What I'm working on

I normally try to get videos out nearly every night, but I have run into some issues that are taking a bit longer to develop.  I am trying to implement rotating the objects in the game in addition to moving them.  While this is rather trivial on one sense, it is proving difficult because I am trying to setup a HUD overlay when you mouse over a movable object.  The overlay has a button for rotating the object.  So far I can get the overlay to appear in the correct position, but one of the issues I am having is that I have set the "onMouseLeave" event to hide the overlay but it doesn't seem to work the way I expected.  The other issue is that I want the overlay to be a circle around the object, but if I implement zooming in overhead mode, the objects will scale up and the overlay will need to scale up as well.  So I'm working on it--stay tuned....

Heads up!

Cliche, I know...oh well.  Here we add a basic HUD component in the form of a crosshair for aiming.  Then I work some trickery to make the crosshair disappear when we aren't aiming.
