I've been working on making a menu system, by drawing boxes for the menus and buttons. It works just fine, until something 3D is created. Then I can't get the 2D to draw over the 3D scene. I even used the draw to front command. Can anyone help me out here? Thanks.

if u want 2d to stay on the screen all the time it has to be updated in the main loop always for it be present each displayed frame.



maybe u try something like this and instead of coloring the buttons place text on the screen in front of a color then grabbing a part of that into a texture location and texturing the button with text or images.

rem What does it Do???:
rem it automatically assigns a 3d plain as a button
rem it will also setup a mouse hot spot according
rem to the 3d button variables at the top of the code
rem
rem using these functions
rem
rem Make3D_btn(objnum,3d_btn_siz,3d_btn_x,3d_btn_y)
rem Place3Dbtn(objnum,X,Y)
rem Check3D_btn_(x1,x2,y1,y2,ms)
rem Delete3D_btn(objnum)
rem
rem easy to adapt for multiple buttons

rem *** The Rotation and colouring

rem What doesn't it Do???
rem It wont change its hotspot size if u wish to change the button

Hey, indi. Thanks. The 3D approach works quite well. I guess I'll have to go back and start over, but at least it'll be easier this time.

Thanks again.

Draw to front/Back, Cls, and Sync are all needed to be used in thr right way. I can get 2d and 3d to work fine together.

Mouse, would you mind edjucating me on this a little bit? I'm having a hard time getting my mind around this stuff. I haven't done that much with 2D before.

Although, it might be better for me to just shut up and actually figure it out.

Well, either way, thanks.
