Continuing in my quest to optimise my RISC OS port of NBlood, I've recently been taking a look at the rendering code. Specifically, the top functions in my profiler's output: the vertical line drawing routines, which are used to draw walls and sprite-based entities.
 
 

The sad death of Jim Nagel has deprived us all of a great advocate for RISC OS and an alround nice guy. It also left a question mark over the future of Archive magazine.
 
The family of Jim Nagel have been busy talking to many people in the Community and sent out an email to all Archive subscribers with updates tonight.
 

So far, 3 videos have been published on youtube to encourage people to use RISC OS.
 

If you are feeling bored in the lockdown and looking for something to do, then Elesar may be able to help. They have put together 2 different bundles of Amcog games, with some nice discounts for you to buy online.
 

Video 2 picks up from the introductory video which showed up how to setup a Raspberry Pi with RISC OS and gave us a very brief overview about how to use it.
 

In the foreground is an ArmBook (i.e. Pinebook) running RISC OS 5.27, from RComp. Behind it is an LG Flatron IPS235 monitor displaying output from RISC OS 5.24 running on a Raspberry Pi 3B+, which sits in the green case, with a red LED shining out.
 

This is the first in a series of free videos on YouTube, aimed at encouraging new users to try RISC OS. It is hosted by Tom Williamson (who we interviewed in 2016). Tom runs the wifi sheep youtube channel.
 

This time, we smuggled our team into Elesar towers to see what they might have hidden up there...
