scrolling text

| Like many programmers out there, I'm trying to develop my own rpg. Does anyone know how I would create scrolling text, like the type found in DiabloII and Baldur's Gate games. |
| ||
| Well, I don't know what kind of scrolling text those games have but would this bit of code be of any use? http://www.blitzbasic.com/Community/posts.php?topic=37964 |

| scrolling from left to right? if you use a pixelfont you can simply change the coordinates every frame.. (in 2d) in 3d its more difficult.. create a sprite, draw your string on its texture. move the sprite across the screen. |

| Using the 2d Text command --- Text x,y,"your string..." , the horizontal position "x" and vertical "y" has to be an integer. A simple loop would allow it to scroll from bottom to top. But I think you want to set it up in a text box. Viewport x,y,width,height -allows you to define a rectangle that plain text will be visible in. Rect can make a colored background and Color can set the text color. In general, I suggest looking at the 2d text commands. |

| Thanks for your help, guys. I guess I should be more specific when I post my questions. When I said scrolling text, I meant from bottom to top instead of left to right. |

| do you mean for a message log, or an NPC conversation? |

| Check this large, little, git out: http://www.blitzcoder.com/cgi-bin/showcase/showcase_showentry.pl?id=gillissie01022003212523&comments=no The above is more for fancy effects - but it is customisable. Doing a small scrolling text system can be done cheaply by creating a few rows of strings and then just copying the contents of each string to the one above it. The text doesn't physically scroll - it more moves up line by line - but some RPG games use that rather than true scrolling. |

| Is is single surface? |

| Slenkar do you mean for a message log, or an NPC conversation? Yes, I intended it to mean NPC conversation, but it could be for a message log as well! Is is single surface? Huh! What do you mean? single surface? Puki Thanks for the info! Will be in touch with you ! |

| Amanda, here's a really simple, 2D, (and not very good!) example of "Text x,y" that I was talking about in my previous message... this same kind of "window" can be used with 3D programs. You can also specify differant Fonts or letter styles and sizes. |

| Thanx guys, These exeamples are writtne for the 2D version of Blitz. Will they work in 3D. I haven't fully researched the ViewPort instruction. Exactly what does it do? |
