VNDS Scripting Language

VNDS .scr file format (source: Digital-Haze):

for any clarification on the usage of these, look at a .scr from another VN

• bgload

  • usage: bgload file [fadetime]
  • looks in background/ for the image and draws it as the background
  • control length of fade in frames with fadetime (default 16)

• setimg

  • usage: setimg file x y
  • looks in foreground/ for the image and draws it at the point (x,y)

• sound

  • usage: sound file times
  • looks in sound/ for the file, loads it into memory(don`t do this with
    • anything over a meg in size) and plays it X times. -1 for infinite
    • looping.
  • sound is expected to be in 22050Hz 1 channel raw imadpcm format.
  • if file is ~, it stops any currently playing sound.

• music

  • usage: music file

  • looks in sound/ for the file,

  • music is expected to be in mp3 format

  • if file is ~, it stops the music.

• text

  • usage: text string

  • displays text to the screen.

  • Prepending string with @ makes it not require clicking to advance

  • if string is ~, it`ll make a blank line

  • if string is !, it`ll make a blank line and require clicking to advance

• choice

  • usage: choice option1|option2|etc...

  • displays choices on the screen

  • when a choice is clicked, selected is set to the value of what was

    • selected, starting at 1.

  • use if selected == 1, etc to go off what was selected.

setvar/gsetvar:

• usage: setvar modifier value

• sets a variable

• modifier: =, +. -

• setvar puts values into local save memory, to be kept in normal save files

  • for things like character flags and such

• gsetvar sets variables in global.sav

  • for things like cleared path flags

• prefix a variable with $ to use it in other commands: text var is $var

if/fi:

• usage:

  • if x == 1 commands
  • fi

• conditional jump

• if true, it keeps reading. if false, it skips till it encounters a fi

• Note: left operand must be a variable, right may be either

  • This is due to either redoing every script to put $ in front of the variables, or just making left not default to string if the variable doesnt exist.

• jump

  • usage: jump file.scr [label]
  • looks in script/ for the .scr and starts reading off that.
  • if label is specified, jumps to that label in the script

• delay

  • usage: delay X
  • X being number of frames to hold, DS runs at 60 frames per second.

• random

  • usage: random var low high
  • set var to a number between low and high (inclusive)

• label/goto:

  • usage

    • label name
    • goto name

  • a goto command will search the current script for a label with the same

    • name and start the script from that part

• Notes

  • titlescreen

    • icon: 32x32 .png
    • thumbnail 100x75 .png

  • To place a variable in a command, prefix the variable name with $ and it

    • will directly replace it. Strings only

• Conversion

  • Images

    • Sprites should be in png format and backgrounds as jpg or png. Alpha transparency is supported for sprites.
    • To avoid color banding, decrease the color depth of the images to 5bits/pixel and use dithering (png doesn't support 5bits/pixel, so store them in 8bits/pixel instead).
    • For background images you should also make sure that they're 256x192 in size.

  • Sound

    • Sound effects should be encoded in aac.

    • use sound conversion tool included with vnds
