Rocks'n'Diamonds

For some odd reason I decided to mess with the idea... just drop these into the graphics folder in your levelset's folder

Steps to reproduce: 1) Turn ON Small Game Graphics (and you probably want to turn OFF Ask On Game Over as well as it will probably interfere) 2) Make the player die in some way 3) Press a key that opens a message, such as F1 or F2 as bound to tape save and load respectively 4) Dismiss the message Sc...

All solved except 50. That one is either a broken design, or has been broken by some RnD behavior change since 1998... The latter seems to be the case. I loaded up rnd 1.2.0 (which actually includes the levelset in question!) in dosbox (the native linux binary didn't work), and it doesn't seem to c...

2. I also got a WASM file of size 64,378,266 bytes initially, but when using "wasm-opt -O2" on it, it only shrinks to 61,650,594 bytes, which is much larger than "under 4 MB". :? Any idea what's missing here to also get that much smaller size? I have no idea. The WASM for me was...

Does it have a noticeable effect on runtime speed, or just download time? I don't know, I couldn't notice a difference in runtime speed in my very limited testing. Can you put an optimized version up at e.g. https://armagetron.kevinh.us/rnd-opt/ ? Sure... though admittedly, I had already replaced t...

I would guess all of the dependencies. Although, it turns out passing the resulting wasm through Binaryen's wasm-opt (-O2) shrinks it right down to under 4MB.

Rocks'n'Diamonds was compiled using Emscripten with some modifications (source and diff below, though admittedly not the best work). It actually wasn't as hard to get running as I thought it would be. If you want to build, you must have Emscripten and use `emmake make` Note that the wasm binary itse...

I think I wouldn't mind being able to see the number in the editor UI as well, could be useful when writing a script to output a level sketch or something and not sure what an element would be

Ah, I didn't even think about trying to research how SDL handles MIDI... based on what you posted, I tried launching RnD with SDL_SOUNDFONTS=/usr/share/soundfonts/FluidR3_GM.sf2 rocksndiamonds ... and it worked! But that means it's launching its own instance of Fluidsynth to use rather than connecti...

Well, I was playing around some other utilities such as using naconnect to connect "Midi Through Port-0" to "Synth input port"... but after that failed I realized... (including applications running under WINE) So... I tried running RocksnDiamonds under WINE, and that does indeed ...

When running QSynth, RocksnDiamonds doesn't seem to pick it up and I get no music on the levelsets which include MIDI files. Other applications (including applications running under WINE) seem to pick the presence of QSynth just fine, though some do require changing the MIDI output from "midi t...

You should be able to create a custom element that does that. I'm not quite sure how to make it collectable without having another custom element somewhere. However, you can make it "walkable over" and change the speed (and the element to empty space) when entered by player.

I'm trying to replicate another Emerald Mine -based game which has some of the characteristics and timing of the Emerald Mine engine, but uses elements (well, just enemies IIRC) that are similar but not quite the same as the spaceship and bug (slightly different speeds [which is alright I suppose] a...

Apologies if this question has already been asked somewhere, but a quick search on these forums didn't reveal anything. Is it possible to use the Emerald Mine engine (or at least replicate it's behavior like moving latency, 1 element player explosion, and the player always facing down when not movin...

Debian 7 Wheezy (64 bit)
3.3.0.1 SDL (built by debian) I'll leave a thing whatever later.
