Why have static water, when we can have flowing water? Flow simulated on CPU, waves and caustics rendered on GPU using single Perlin noise texture and definitely too much math. All realtime of course. #gamedev #indiedev #beardedtd

Playing with a water shader: surface-level diffuse and specular reflections + caustics projected onto the terrain. Looking pretty good for only using a simple Perlin noise texture. #gamedev #indiedev #beardedtd

@MartinDotNet @ChrisAnnODell @dylanbeattie Thanks!

@amulware @ChrisAnnODell did a video on it youtu.be/Ah13fl6VZag @dylanbeattie wrote a blog @dylanbeattie/why-your-talk-wasnt-picked-for-ndc-9f19366d8a43" target="_blank" rel="nofollow noopener">medium.com/@dylanbeattie/… Theres loads of factors, it's kind of a Goldilocks, but the main thing is to put yourself in the shoes of someone reading it, and work out whether you'd choose it.

The acceptances are going out for #ndclondon 2020, and unfortunately, so are the rejections. If you weren't chosen, you should know that 9 of us went through over 1000 submissions to fill just 90 slots. 1/3

@MartinDotNet Any tips for how to put more effort in to up our chances (and make your job even harder ;)) next time? How long/detailed of a description do you like to see? What should it contain? Does it help to give details about me/my qualifications? Do you prefer new or already given talks?

For those that got in, know that you earned it. The most consistent theme for being accepted was people whose effort to curate their submission shone through I can't stress enough that when the standard is so high, those that put in the effort have a leg up on everyone else 3/3

@sarahcarmody @danipanteez Wizards vs Wild Magic Sorcerers? ;P

two types of DnD energy xD

@quasidog1 Clerics combine heavy armour and proper spell casting. Healing is as essential to them as to other classes. It’s great to have some in the party, but there is plenty other roles they can fill.

@CodeLumpN @CasualEffects It scales very very well, and can be parallelised trivially! I did it: github.com/amulware/fluid… (see recent tweets for gifs) but I think Morgan is looking for a side view, not top down. Though perhaps the same approach could be adapted still.

I want to make a very fast water simulation for a 2D building game on a grid, like Terraria. I don't care about realism except for incompressibility and stability--water should go around U bends, form waves but not vibrate, and not lose [much] volume. What's the state of the art?

My shader inspiration for today. Also loving the style in general!

@CarnivorousMeat @d_percentile Unless attacking uses limited resources (spell slot/ammo) in which case making sure you hit one attack can very much be worth two actions. Nothing worse than missing a 5th level Guiding Bolt or wasting that Arrow of Slaying.

@d_percentile This is similar to #DnD5e If you cast True Strike on yourself, you gain advantage on next turn (rolling twice taking higher single). If I just attack this round, and then again next round normal: I have still rolled twice, except with the option of a possible of hitting twice.

Hey rpg people I have a #troika rules question. Why would you aim? You either take two separate shots with two chances of hitting or wait and take the best of two rolls (so you can only hit once).

@Atrix256 I go "breadth first" a lot. Really requires being in the zone, since you have to keep so many different things in mind. Can't judge if the result is better or worse than a more organised approach. Sure can get a lot done quickly, though, if you know what you're going for.

Oops.

The shader of the week is 'Protean clouds' by nimitz : shadertoy.com/view/3l23Rh

Last one for today - check those waves ~~~~~!

Added arbitrary ground height. I did not expect this to work so well and so easily - a two line change in the actual algorithm 😱

Playing with some (simple) fluid simulation, looking surprisingly good for how basic the code is.

@BarrySkellern Disclaimer: i haven’t actually played any of them since 1404, so can’t be 100% sure how representative they are. But from what I’ve seen, it’s close enough.

@BarrySkellern I got a lot of nostalgia for 1692 and 1503 but unless you have a windows 98 machine standing around, you’re probably better off trying 1701 or 1404, both quite decent. If you do, consider checking both campaign/scenarios and endless mode, they can appeal to different people.

@EricLengyel Right, I considered only a single vertex. I now see how quite complex polygons with many concave vertices can fit this criteria. The one thing this reminds me of is how star shaped bastion fortresses were built to cover all their angles... no idea if that’s at all helpful :D

@amulware Having all exterior angles ≥ 90° is not sufficient. Think of a square U-shaped polygon.

I need a term for a polygon having the property that any ray starting on an edge (but not at a vertex) and pointing along the outward-facing normal does not intersect the polygon again. All convex polygons obviously satisfy this property, but so do a lot of concave polygons..

@EricLengyel Otherwise maybe.. non (exteriorly) self projecting polygon? Since non of the sides project onto each other exteriorly.

@EricLengyel This is... polygons with all interior angles <=270° or ‘outside angles’ >90°? Between acute, obtuse and reflex angles, i don’t think there is a good name for these... But maybe something like.. outwardly obtuse polygons? Obtusely concave polygons?
