Re-renders games in 3D instead of 2D.
The 3D rendering is done through babylonjs, a 3D WebGL rendering engine.
Notes:
- The smooth moves hack is included to avoid jerky camera motion when the player moves
- The transparent sprites hack is included with this since most 3D games would need it
if wanted, you can prevent it from making things transparent by making the isTransparent
function in the options always return false
- Exit transition effects aren't implemented
- The scene variable is exported, which means it's available at `window.hacks['3d'].scene`
this is useful for debugging, or in combination with the JS dialog hack
- No camera/mesh collision is included
- The 3D library included is very large by hack filesize standards
The Biggest Note: If you try this out and think "this would be great if only it did X instead of Y",
it probably can with a bit of customization!
Naturally there are dozens of potential ways bitsy could be translated to 3D,
so I focused on covering what I imagined to be some of the most common use cases.
If you need help customizing the hack to achieve a different style, feel free to reach out.
The hackOptions below have relatively thorough documentation,
but make sure to check out https://github.com/seleb/bitsy-hacks/wiki/3D-Hack-Examples
for examples of different setups if you're new to 3D.
additional features to help make more fancy 3d scenes from bitsy editor:
* make arcs, bridges, ceilings, multiple floors, and such by layering
bitsy rooms on top of each other. add tag-function '#stack(stackId,position)'
to the names of the rooms you want to render together
for example you can have rooms named 'theater #stack(a,0)', 'stage #stack(a,1)' and
'catwalks #stack(a,4)' and they will be displayd at the same time, the 'stage'
right on top of the 'theater', and 'catwalks' three tiles higher than the
'stage'
'stackId' should only include letters (no numbers and special characters
please), it specifies the room stack.
rooms in the same stack will be rendered on top of each others, in layers.
'position' is the hight at which you want to display a
specific room. you can use negative numbers and floating points too, like
'#stack(fjk,-3.5)'
note that two rooms in the same stack can be positioned at the same height
(useful for layering drawings themselves right on top of each other to make
use of more colors and other nifty workarounds)
* specify the mesh to use for a specific drawing by appending its name with '#mesh(type)'
there are following mesh types available:
- plane: plane standing up straight
- billboard: like plane, but turns to look at the camera
- box: standard cube
- floor: plane flat on the ground
- tower1, tower2, up to tower16: box variations that are taller and tiled
- wedge: base mesh for wedges, facing left with its slanted side
- empty: use this one to make the drawings invisible
you can have drawings with the names like this using this tag:
'sign #mesh(plane)', 'water #mesh(floor)'
don't forget that you can combine '#mesh(type)' with transform tags
* transform tags: translate (move), rotate and scale by adding tags to the drawing's name
useful for making more complex shapes and more organic silhouettes by shifting
models a bit off the grid, and configuring plane-type meshes to face a specific direction
#t(x,y,z) for translation, #r(x,y,z) for rotation (in degrees), #s(x,y,z) for scaling.
#t(1,0,0.5') and '#t(1,,.5)' are both examples of valid input
omiting the number is the same as writing 0. note that this won't change anything on the given axis
for rotation and translation, but it will for scaling
* add #transparent(true)/#transparent(false) tag to the drawing's name to set
transparency manually. sprites and items are transparent by defualt, and tiles are not
check this out to learn how to work with wedges conveniently in the bitsy editor:
https://github.com/aloelazoe/bitsy-hacks/wiki/how-to-use-wedges-with-3d-hack-and-replace-drawing-hack
here is a template with 12 pre-configured wedge drawings you can use with 3d hack and replace drawing hack:

if you have questions, suggestions or constructive feedback about additional features
introduced in my fork, feel free to reach out on bitsy discord or twitter (aloelazoe)
enjoy have fun with verticality triangularity and whatnot!!!

HOW TO USE:
1. Copy-paste the contents of this file into a script tag after the bitsy source
2. Add the tags described above to the names of the rooms and drawings in bitsy editor to use additional features
3. Edit hackOptions below as needed
