I have a healthbar in my game designed by the a poster in the code snippets forum. I put it in, but it does not show on top of my 3D game. I call the function once per loop. I use the Draw to Front command, but that hasnt helped. Here is my code:

Draw to Front
...
   rem Minimum, Maximum, and Current HP
   MinHP# = 0
   MaxHP# = 200
   CurHP# = 200

rem How many pixels long do we want the bar
   pixlength = 500
   pixheight = 10

rem XY location of bar on the display
   x = 275
   y = 30
...
do

rem Update input data
   UpdateKeyHold()

rem Display screen data
   set text size 22
   text 0, 0, "FPS: "+str$(screen FPS())
   text 0, 30, "Enemies Killed: "+str$(enemys_killed)

UpdateFollowCamera()
   UpdatePlayer()
   healthbar(x,y,MinHP#,MaxHP#,CurHP#,pixlength,pixheight)

UpdateEnemyAI()
   UpdateElevator()

RunCollisionPRO()

CheckExit()

sync

loop
...
function healthbar(x as integer, y as integer, MinHP# as float, MaxHP# as float, CurHP# as float, pixlength as integer, pixheight as integer )
   rem The Math

rem some conditions so that you don't go negative on certain values
   if CurHP# < MinHP# then CurHP# = MinHP#
   if CurHP# > MaxHP# then CurHP# = MaxHP#
   if pixlength < 1 then pixlength = 1
   if pixheight < 1 then pixheight = 1

rem Change our values from Integers to a percent so that we can see how much of the bar needs to be filled
   pBar# = CurHP# / MaxHP#

rem Get the percentage of the bar to be filled
   thebar = int(pixlength * pBar#)

rem Draw the bar
   box x,y, x + thebar, y + pixheight
   line x + pixlength, y, x + pixlength, y + pixheight
   line x,y, x, y + pixheight

endfunction CurHP#

+ Code Snippet

Draw to Front
...
   rem Minimum, Maximum, and Current HP
   MinHP# = 0
   MaxHP# = 200
   CurHP# = 200

   rem How many pixels long do we want the bar
   pixlength = 500
   pixheight = 10

   rem XY location of bar on the display
   x = 275
   y = 30

   UpdatePlayer()
   healthbar(x,y,MinHP#,MaxHP#,CurHP#,pixlength,pixheight)

   UpdateEnemyAI()
   UpdateElevator()

   RunCollisionPRO()

   CheckExit()

   sync

loop
...
function healthbar(x as integer, y as integer, MinHP# as float, MaxHP# as float, CurHP# as float, pixlength as integer, pixheight as integer )
   rem The Math

   rem some conditions so that you don't go negative on certain values
   if CurHP# < MinHP# then CurHP# = MinHP#
   if CurHP# > MaxHP# then CurHP# = MaxHP#
   if pixlength < 1 then pixlength = 1
   if pixheight < 1 then pixheight = 1


   rem Change our values from Integers to a percent so that we can see how much of the bar needs to be filled
   pBar# = CurHP# / MaxHP#

   rem Get the percentage of the bar to be filled
   thebar = int(pixlength * pBar#)

   rem Draw the bar
   box x,y, x + thebar, y + pixheight
   line x + pixlength, y, x + pixlength, y + pixheight
   line x,y, x, y + pixheight

endfunction CurHP#

Please help me get the healthbar to show on top of my 3d action.
thanks

You could try drawing to a bitmap, geting an image from the bitmap with get image and making a sprite with the image.
Sprites should show on top of the 3d stuff.

No, dont make a bitmap, at the begining of all your code just type "Sync on" and then "Draw to front" that makes any 2D come to the front and "Draw to back" will send it to the back!

good luck

fart like you've never farted before!!!

@Jaze - I had a code snippet in my first post. I do have "sync on" and "draw to front" but my healthbar still isnt showing up. I need an alternative means of displaying my 2d atop 3d.
thanks anyway though

I am trying to place box/lines on top of my 3d objects/world. I tried using the draw to front comand, but no luck.

I'd use

+ Code Snippet

set camera view xstart,ystart,xend,yend

where xstart is the left of the 3D part of the screen, ystart is the top of the 3D part of the screen, xend is the right of the 3D part of the screen and yend is the bottom of the 3D part of the screen. Everything else will just be 2D. That's what I do for games - leave a space at the top or the bottom. That means that no 3D stuff gets in the way and you can do text and stuff as well.

Am I the only one here who's really confused?

It's working for me, are you using dbpro or classic?
