I have a stamina code, that I have added into a 3D world.
It works as expected but continually flickers during gameplay.

Can anyone suggest how to prevent the flicker?
The thing that comes to mind is to use bitmaps and draw to front to overcome this problem.

Am I on the right track.

Any Help will be appreciated

maybe youre updating the image every loop, when you really only need to if it has changed?

I appreciate the interest in this post, Sorry for the lack of posting any code.
Castle Rustler was right I was updating the image every loop, my father had a look at it and that was what the problem was.

Once again thanks everyone I hope we can converse again sometime.

Yours Sincerley

For your problem you could possibly do something like:

Be sure to put it inside your loop

Tigger,

You could use the Time command as part of a calculation of the stamina increase.

Eg if you want to increase stamina by 1 per 10 seconds, and stamina last increased 20 seconds ago, stamina would increase by 2 or
(1/10)*20

Every time you increase the stamina pass the current time into a variable (eg lastinc) and then later, when you want to check when you last increased stamina, compare the current time to that variable. If it's less than 10 seconds, don't increase stamina, let the program carry on and do other things. Whenever it becomes 10 seconds or more... you let it increase relative to time passed.

This allows stamina to increase as a function of time. However I believe the real pros build "pulses" into games, say 20 pulses per second or so, and then everything is a function of the pulse. But I've no idea how that would work.

Hi Tigger,

In my current post from the 20-liners forum, there's an example of a stamina bar that gradually decrease according to the frame rate.
The bar is a 3D plain object (faster than a bitmap), and I think the code isn't too hard to understand (lots of comments). Not too fancy, but that's a start...

Take a look, it might help...
