been asked a million times as i found the posts on search, but none of them had any code, and the codebase doesnt have anything either.

can someone just post a tiny snippit?

im trying to lock a 3d plain textured with an image to the camera etc but no luck as of yet.

will keep trying but if someones got a nice little example of how to lock the image on screen - i dont mind if its a 2d sprite or a 3d plain - that would be nice.

i dont have any worries about making the inputs for the hud as it seems quite easy with \"create bitmap\"

thankyou please,
Paul

OR

I spotted a command in the help file that would do the trick for a hud. You might have to make a separate image for each resolution that you might have to display, but it seems to work pretty good.



The last 1 on the paste image command tells it to make all pixels that are rgb(0,0,0) transparent.

well i've blown all my hud code away after several hours of messing about and getting nowhere near fast enough or nice enough looking for me.

I've ended up using:

load image.
paste image.

combined with the transparency flag on paste image, and exporting my hud as a png with alpha channels.

Works like a dream - why did i even both trying "lock image to camera", - i just paste my image each program cycle/loop.

only other thing is to make an image on the fly with create bitmap but im not sure about how to get the transparency just right on bitmaps (probably end up texturing a plain with it then set object trans..)

It's worth getting to grips with using plains for a HUD. The ability to make better eye-candy is far greater. For example, you can rotate (on the X and Y axis as well as Z), scale and use shaders. They also tend to be faster than sprites or pasting.

what do you mean by rotating them on x y and z? why would i want to do that with a hud design? just wondering what you had in mind?

By using textured plains you are manipulating 3D objects, which if you do it right can give you a more 3D look and feel to your HUD.

One other benefit to using object not mentioned is that they will automatically stretch to the same relative scale if you change resolution.

i.e. If your object runs halfway across the screen, it will do so no matter which resolution you use, while pasting the image will cause it to draw a specific number of pixels across and will take up a different proportion of the display when you change resolution.
