# Dramatic Shape Voxel Mod
|
|
|
|
A mod for the [Pokémon Gen 1 Recompilation
|
|
Project](https://github.com/bryanthaboi/pokemon-gen1-recomp-project).
|
|
|
|
The overworld as a 3D diorama. Terrain is extruded into real geometry,
|
|
occlusion comes from a depth buffer rather than a y-sort, characters stand
|
|
as leaning sprite slabs, a shadow map throws real cast shadows across
|
|
whatever they land on, and an optional tilt-shift pass sells the
|
|
miniature-model look.
|
|
|
|
Water is a surface rather than a texture lying in a hole. It is a field of
|
|
one-pixel-wide voxel columns, each standing a whole number of pixels tall and
|
|
rising and falling as waves — found by walking the view ray through them in
|
|
the shader, so a crest hides what is behind it and shows you its lit side,
|
|
with no extra geometry anywhere.
|
|
|
|
And it reflects. The sky it stands under, in the same bands, the same dither
|
|
and off the same clock, so the lake and the sky above it meet at the
|
|
waterline with no seam. The sun or moon hanging in it, at the size the
|
|
painted disc is drawn, craters and all. Whoever is standing beside it —
|
|
walkers, NPCs, the two Pokémon in a staged battle. And on **FULL**, a
|
|
screen-space ray march adds the rest of what is on screen: the shoreline, the
|
|
trees behind it, the buildings across the bay. How much of it shows is
|
|
Fresnel, so the top rung is a mirror and a looking-straight-down rung is a
|
|
pond, off the same water.
|
|
|
|
And battles fought on that world rather than on a white field. When
|
|
something picks a fight the map's NPCs are culled, the engine's own wipe
|
|
plays over the empty map, and the battle draws over the nearest patch of
|
|
clear ground — shot over the shoulder, the player's mon low and left and
|
|
the enemy high and right, with a slow parallax drift behind them and a
|
|
depth-of-field pass that keeps both of them sharp.
|
|
|
|
Purely presentational. Nothing here reaches collision, movement, triggers
|
|
or scripts — it changes what the world *looks* like and nothing about what
|
|
it *is*. The battle arena is where the **camera** goes, not where anybody
|
|
goes: no cell, facing, flag or warp is written, so the player is standing
|
|
exactly where the fight found them when it ends.
|

## Controls
|
|
|
|
Every key is free-roam only, and each one is also a row on the OPTIONS
|
|
menu.
|
|
|
|
| control | does |
|
|
| --- | --- |
|
|
| `3`, or the **VOXEL** options row | OFF → 15 → 35 → 50 → 75 → OFF (camera pitch) |
|
|
| `5`, or the **V-GRID** options row | OFF / ON — a one-pixel wireframe on every voxel |
|
|
| `6`, or the **T-SHIFT** options row | OFF → 1 → 2 → 3 → OFF (miniature blur) |
|
|
| `7`, or the **V-CURVE** options row | OFF → 1 → 2 → 3 — bend the world over the horizon |
|
|
| `8`, or the **3D-BTL** options row | ON / OFF — fight on the map instead of on a white field |
|
|
| `9`, or the **WATER** options row | FULL / SKY / OFF — waves and reflections on water. **SKY** gives the surface its pixel-tall wave columns and puts the sky, the sun, the moon and the cast in them; **FULL** adds a screen-space ray march that also reflects the shoreline, the trees and the buildings standing behind it |
|
|
| the **BACK SPRITES** options row | OFF / ON — keep your own Pokémon on the battle menu, seen from behind in its classic slot, instead of standing it on the map; the foe is still out there. Only on the menu while **3D-BTL** is on, because it decides nothing without it |
|
|
| the **DAYTIME** options row | SYNC / DAY / NIGHT / DUSK / DAWN / CYCLE — what time it is outdoors, on the diorama *and* on the flat 2D world; held at SYNC (and off the menu) while VOXEL is FULL |
|
|
|
|
**3D-BTL** is on by default and is independent of **VOXEL**: battles draw
|
|
on the world whether or not the free-roam camera is pitched over.
|
|
|
|
Two of the engine's own rows are taken away while this mod is installed:
|
|
**TILT**, which is the flat fake of what this mode does for real, and **GBC
|
|
FX**, a full-screen present pass over the top of the diorama. Both are held at
|
|
off rather than merely hidden — a row that is not there cannot switch off a
|
|
value an older save arrived with. Uninstall and both come back, at whatever
|
|
they were last set to.
|
|
|
|
Everything the battle screen draws as a box — the two HUD blocks, the text
|
|
box and the menus over it — sits on frosted glass rather than on the white
|
|
field it used to have behind it: the world underneath, blurred and laid back
|
|
down translucent, with the ink flipping white where the ground it lands on is
|
|
dark. Nothing the engine draws inside a box moves; only the paper is gone. |
