wow well done everyone, there's some seriously good work coming in from all of you so thank you.
I've been a bit off-grid recently, unfortunately I suffered a bereavement which knocked me for six as some of you may know.
I'm going to try and do a catch up session this week and work through all the new stuff and get it integrated into a new demo.
To answer a question, background images I've found work well at 640x480, or 800 x 600 as PNG files, I find it keeps in with the retro style and doesnt look too hi rez.The background image is a fixed plane (stayes relative to the camrea), I guess it could be animated if we needed to persue that avenue.
I don't know how many of you have had time to play with the engine, but you can already add your own models to levels in the demo to see how they look, if anyone is interested, I'll explain how.
Anyway, keep up the good work everyone! Hopefully we arent that far off finishing the engine on this and then its just modelling left.
