Reuse values with variables

Variables hold values that should be reused across designs without living in a card-by-card dataset.

Project variables in Gamepiece Studio A variable changes one shared value; a dataset changes values from row to row.

Available variable types​

Variables can hold text, a number, a boolean, a colour, or an image. They do not have an options/enum type.

Good uses include:

  • Game title and copyright line.
  • A shared rules version.
  • Brand colour.
  • Publisher logo.
  • A global on/off treatment used by expressions.

Use a dataset column instead when the value changes between cards or pieces.

Create and bind a variable​

  1. Open Variables.
  2. Create a clearly named value and choose its type.
  3. Open a design layer or supported setting.
  4. Choose the variable from its binding options.
  5. Change the variable once and verify every important use.

Rename or delete safely​

Names should describe purpose: rules version is clearer than text 2. Before deleting a variable, inspect designs that depend on it. A missing variable can produce an unresolved value or an export QA error.
