hello again fellow programmers.

i'm thinking about putting a scrolling credit system on the main screen when the games loads so a can give credit to all the ppl who have helped me out.

the only problem is i don't know how to do it. i can put text on the screen no problem. thats very easy to be honest, but to scroll it so far and have it fade in an out at the top and bottom is way beyond me.

i wonder if i'll have to make a seperate viewbox (type of window) and show the text in there so as not to make it look tacky and cheap

thanks to any1 who helps me out

You might also want to look in the codebase, there are a couple of examples there too.

Any truly great code should be indisguishable from magic.

Without looking at this examples, I can tell you that all you need is the CENTER TEXT command to position the text, the INK command to fade the color in and out, a string array to hold your data, and a FOR/NEXT loop to drive it all.

The tricky part is to mix in resource loading and keep the text scrolling smoothly.

I'm sure a generic thank you to the forum will suffice with specific names for those that help you the most. Afterall, most folks that reply here are doing it just to be helpful (or at least educational or entertaining.)

thats true taz

just one other thing. a little problemo has arisen from the depths of DB hell. i turned the backdrop off at the begining of the program and as u know the screen doesn't update like it does in 3D.

what i get is a white smear running up the screen and there isn't delete text function that i'm aware of. i found out when i put the code in.

is there a way to do it. bareing in mind that i ain't got a single colour background. its got a gradient.

i don't do things easy do i

Ah yes.. the smear. I know it well. When I did the scrolly in my hexapawn game demo I ifnally got so frustrated with it that I just drew a background colored line at the bottom (top?) of each line to erase any old text. Since the line moves upward with each scrolled line of text, it performed the erase I needed. If you can do that in your situation, it makes it easier. If not, then you have a image/sprite paste problem I'd not envy.

i changed how i did it.

it now shows on the game exit not on the title screen. makes life easier when i got the backdrop on.

still i got something what works if not exactly the way i wanted it to.

i did think about the sprite thing but though against it

Yeah-yeah, I agree. The sprite thing can be a bother...
