Hallo,
I want to scroll textlines with different colours. But if I use dbInk(),dbSetTextFont() or dbSetTextSize() the scrolling slows down. Are these commands so slow?

Thanks for help

Yes they are, those functions are best not used in realtime.
I'd suggest you to look into creating a bitmap font system, with a bit of colour blending you can change colours of those with ease and yes, they run very fast.

Also changing the text font and size will have a huge impact on speed as it has to reload the new font.

A little while ago, I wrote myself a sprite font system (No kerning, but I didn't require one for my purposes...) Here's the code:

And attatched is a bitmap font. Everything's pretty well labeled, so changing the system shouldn't be hard. It runs by reading a string's ASCII codes, and pasting the apropriate letter at a calculated position. Nothing special.

Using this function, you can use multiple font images at no cost to the game's performance, as each font requires only ONE sprite!

It's been fun: So long, TGC!
