# World6-travelmap
|
|
I made a little program for displaying a simplistic graph of nodes and edges to
|
|
make a travel network with calculated distances... specifically for my Minecraft
|
|
World.
|
|
|
|
Data must be in a map.json file. `nodes` is an object with named arrays of info.
|
|
Each node is an `x`, `y`, and `z` position. The optional 4th item is `true` to
|
|
display the node's name, a string to display *that* as the node name, or `false`
|
|
to completely hide a node. `edges` is an array of arrays of two names of nodes.
|
|
An optional 3rd item can be set to `false` to hide an edge, or a string for a
|
|
custom label. `edges` can be nonexistent.
|
|
|
|
Pan with WASD or arrow keys.
|
|
Zoom with +/- keys.
|
|
`r` to reload the default map.
|
|
|
|
You can drag and drop a JSON file to load it.
|
|
|
|
Both nodes and edges can have an extra object with metadata, some of which is
|
|
used by this program. An array called `offset` will adjust the positioning of
|
|
labels. An array called `color` will set the color via 0 to 1 RGBA values.
|
|
|
|
Added `areas` which are exactly like nodes except that they always draw a white
|
|
label and can have a custom radius specified. Drawn between edges and nodes.
|
|
Use transparency. 25% works well.
|
|
- `box` can be an array of width/height to draw a rectangular shape instead
|
|
- `radius` can be an array of x/z radii to draw an ellipse instead of a circle
|
|
- `mode` can be "line" to draw an outline instead of filling
|
|
- `image` can be a file path, in which case `size` must be an array of desired
|
|
width/height
|
|
- (path relative to the JSON file? or relative to the executable?)
|
|
|
|
Images are only loaded if they will be displayed.

## Example JSON
|
|
|
|
```json
|
|
{
|
|
"nodes": {
|
|
"TestA": [100, 0, 100],
|
|
"TestB": [150, 0, 200],
|
|
"TestC": [300, 0, -200, true],
|
|
"TestE": [1200, 0, 200, "Displayed Name"],
|
|
"TestFarLeft": [-200, 5000, 50],
|
|
"TestFarBottomRight": [1200, 0, 2000, true],
|
|
"Hidden Node": [0, 0, 0, false]
|
|
},
|
|
"edges": [
|
|
["TestA", "TestB"],
|
|
["TestA", "TestC"],
|
|
["TestB", "TestC"],
|
|
["TestC", "TestE"],
|
|
["TestE", "TestFarLeft"],
|
|
["Hidden Node", "TestC", false]
|
|
]
|
|
}
|
|
```
