Rocks'n'Diamonds

this tape for level 4 of niko böhm's tutorial ("bombs and dynamite") demonstrates a graphical bug at 0:32 where the old position of the player graphic is never cleared after precisely walking through an explosion. as expected trying to walk to this spot again afterward causes the space to ...

after downloading theonyxguy's "Level Shuffle" levelset (from this post ) i drag-and-dropped it onto rnd, notably it did not say "game must restart after loading new levelset!" like with most levelsets. afterward, i found a few issues: 1. the custom graphics did not load until i ...

• Emerald Dash 04, level 00: ...It doesn't look like dummy players can die from falling boulders? Otherwise this level would be impossible to finish.

for the record this is consistent with how dummy players work in boulder dash (they only kill the player if an enemy is adjacent to them)

it's worth noting boulder dash 3 is quite a mess in general: https://www.lemon64.com/forum/viewtopic.php?t=2051 . although arno's bd3 page http://boulder-dash.nl/bd03.php?lang=en implies intermission 2 (there "Int 2") should be possible. this might be worth asking http://www.boulder-dash.n...

for reference, mission game: http://www.mission-game.com/ (very alan bond bd2k3-esk graphics) and worm plex: https://www.amazon.com/Perun-Labs-Worm-Plex/dp/B00CUEJDEI right away mission game has a "fire" object that was not originally in supaplex, and worm plex seems to have some kind of c...

for what it's worth this is also an issue on emeraldmines.net, which uses the same EM engine as RnD: http://emeraldmines.net/play/src/dev.html?disk=99/14

to visually clarify: in the EMC engine, pushing this spring right will result in it running over/"slurping up" the robot (yielding the amount of points specified by "Score for slurping robot") and meeting the spring bouncer. in the RnD engine it will just stop at the robot. slurp...

the emc spring object has a parameter for "Score for slurping robot"; this refers to how in EMC if a spring encounters a robot on its path it will destroy it much like a yamyam destroys a diamond and continue moving. and indeed it works that way in the EM engine. but in the RnD engine spri...

odd, i also use redshift (1.12) and this has never been an issue for me. i'm on debian 12 with xfce 4.18

Neat! Although the question is are they going to be dependant on the "Snapshot mode" setting? I'm pretty sure they're only going to be available when it's ON. this is actually already a dilemma that exists with the "show undo/redo buttons": if that option is on but snapshot mode...

currently the undo/redo functionality for game engine snapshot mode is only available as a button in the user interface that you click (and only if you have "show undo/redo buttons" enabled). that's a little inconvenient as RnD the most part does not use the mouse cursor ingame. an optiona...

"override custom artwork: yes" means always override custom artwork. "override custom artwork: no" means never override custom artwork. "override custom artwork: auto" means... what? only override custom artwork when it isn't the same as the current artwork? but that wo...

Would you share the "natural intelligence" algorithm? https://imgs.xkcd.com/comics/trained_a_neural_net.png I think that whatever visual parser is used[...] it would have a much easier time parsing levels from Supaplex, where there are not (I think) different forms of monsters based on di...

Otherwise, every viewer has to start by re-creating the levels themselves in the editor (which I'm sure is super easy to get wrong...) Or, well, alternatively, has anyone else gone through the reconstruction process and can upload these as usable level data?! :) (or maybe that software recently use...

Is there any way this bug could be turned into a feature? [...] These clones were clones of the C64 version of Boulderdash, but I remember some of them differed by having a) pumpkins instead of one of fireflies or butterflies (no change in behaviour); b) allowing true diagonal movement. both of the...
