Re: H-Tron

I worked on the character choices for this type of plotting. Ill find and post what I have so far. A quick test with the "Chroma Program Enhancement Creator" reveals the secret behind Andy's plot function: HTron_Chroma_Colour_Test.jpg @Andy: very clever! I never thought that it would work that way....

Re: H-Tron

If have seen that Siggi has written some z88dk ZeddyNet libraries , so he definitively knows how to code in z88dk and how to use ZeddyNet. And my game code is rather simple and hopefully well-documented, so in theory it should be possible to join our forces and try this. However, I have no idea if t...

Re: H-Tron

I don't know how this game is constructed as I don't have the brains to understand such things but what I do know is that it isn't just simply "plotting". After every right/left turn it uses a combination of a few different printed characters for the vertical and horizontal trails not simple plots,...

What I meant to say Robert is I will do the UDG if that is ok?
Ah, I see, ok. If you think you can further improve the game, try it, no problem for me. Although I don't know yet what can be done in terms of UDGing to such a game that only plots, but I will probably soon find out. :)

Re: H-Tron

I forgot to mention that I have included the source code in the zip. I hope that this will help other z88dk newcomers with their own work. iirc my AI logic was more random that anything, think I used the ROM contents as a very crude random number gen, to choose a new direction if a collision was imm...

Games don't PLOT. Just sayin' ;)
But maybe a game could first plot and then scroll. :D

If anyone wants to turn my "simple full-plot scrolling" demo into real scrolling as described by Andy: go for it!

Re: Plot function in z88dk

I have made a little Moon Patrol-style scrolling mountains demo using Andy's zxplot function. zxplot_mountains.jpg It is still too slow to be used for anything useful, but it is unbelievably fast compared to if it had been made in ZX Basic... It also still lacks double-buffering - I have seen in the...

Re: Chroma 81 - SCART and Colour interface for the ZX81

I have made two more modifications to my Space Raiders .col file: the screen border is now black and the base line grey. This should now really be the final version. [Edit: NOT. The final version is included in the Colourisation Tutorial pack which can be found here . Outdated attachments removed fr...
