# Set Value  The `Set Value` event can be used to change the value of `value definitions`. ## The options You can select the `value definition` to be changed, then the `type of change`. Then you can determine the new `value` to be set. + `[to be]` will set the definition to EXACTLY the given value. + the others will use the existing value and change it in the given way. These only work with numbers. By toggling the little cube icon, you can use a random number instead of the fixed input field.
