The flu still lingers, but just started again with Chuckulus.... Found a bug that I swear wasn't there when I got ill. What's the 'GO!' bubble doing over there ??! 🙄
Put in a key control set option, so you can choose between 'ZX:/ RETURN' and '<>AZ SPACE' to control Harry ! Which would you choose?

Now we're thinking with... uh... whatever this is.
OK! 51 balls *but* single buffered 8x8- Moving to 9x9's gonna cost some cycles! Can only get to 24 with double buffering, long way to go.
This is pretty fun! Cheers for pulling me back into the game @0xc0de.bsky.social and @snuggsy187.bsky.social

Many thanks to @rasto1968.bsky.social and @0xc0de.bsky.social for testing a very early beta version of Chuckulus.
I'm ploughing through *cough* a few issues they have bought up, one of which was the scrolling appearance of the DUCK cage at the top of level. I knew it wasn't right, that's better !

Back to this version of the game. I have added the score board gfx and related code to calculate the score etc. Game running at 50fps, still need to do tile animations. youtu.be/A6hO-ZApOjQ #GameDev #RetroGame

Feel I'm getting a fairly solid version of #bomberman in place for my next #picotron project. CPU players are something I'll worry about later on. Want to get the single player and co-op basics in place first.

My #picotron #bomberman game has had a facelift. I love the simplicity of the NES & PC Engine graphics & also the arcade version. Have "borrowed" some of the tiles etc for now & player sprites are a bit of a mash-up - but I like them.

Just found this on a random USB stick....
I guess I was pondering this while doing 'Fortress' for the Acorn Electron (which I shall return to and finish one day), as it could use a lot of the same procedures.
Mode 1 with palette change halfway down the screen, changing red to green !

Talking of Acorn Electron Fortress, this is how far I've got with it.... slightly stalled due to stable framerate issues (and Chuckulus !).... plotting that giant wall causes the poor old Elk some problems now and again !

Another day, another level designed !
Splatted that keyboard bug (which wasn't - just an issue with the Harry movement logic), plus a few other things I wasn't happy with / hadn't noticed before !
The list of 'things to do' is very short...... at the moment ! 😱

Another thing of the list: in-game text 'bubbles'
The 'GO!' bubble is a sprite, as it rises up the screen at start of play
The others are 'simply' plotted text (inverted colours) and then some calculations to plot the bubbles around it 🤯 - not enough memory left for all 4 of these to be sprites!

Level 5 done - this highlighted a certain key combination that caused problems in the past (a kind of key clash thing)..... now the bugs mutated into a 'loop until you stop pressing these keys' feature !
Should be easy to find and fix - bit weird though !
