Navigate normally returns true but will return false if an error is encountered.Ĭontext variables for navigation are explained in the article navigate between screens. The App.ActiveScreen property will be updated to reflect the change. Set the OnHidden property of the old screen, the OnVisible property of the new screen, or both to make additional changes during the transition. This record is the same as the record that you use with the UpdateContext function. As an optional third argument, pass a record that contains the context-variable name as a column name and the new value for the context variable.
GAME MAKER SCREEN WRAP BEFORE LEAVING SCREEN UPDATE
You can use Navigate to create or update context variables of the new screen. The current screen slides out of view, moving left to right, to uncover the new screen. The current screen slides out of view, moving right to left, to uncover the new screen. The new screen quickly replaces the current screen. The current screen fades away to reveal the new screen. The new screen slides into view, moving left to right, to cover the current screen. The new screen slides into view, moving right to left, to cover the current screen. In the second argument, specify how the old screen changes to the new screen: Transition Argument In the first argument, specify the name of the screen to display. You can use either function only within a behavior formula. Use the App object's StartScreen property to control the first screen to be displayed. If you've used another programming tool, this approach is similar to passing parameters to procedures. You can use this approach to pass parameters to a screen. You can use Navigate to set one or more context variables for the screen that the formula will display, which is the only way to set a context variable from outside the screen.
The user can then navigate back to the original screen and confirm that the slider has kept its value.Ĭontext variables are also preserved when a user navigates between screens. For example, a user can change the value of a slider on one screen, navigate to a different screen that uses that value in a formula, and determine how it affects what happens in the new screen. You can build formulas that refer to properties of controls on other screens. Screens that aren't currently displayed continue to operate behind the scenes. In that formula, you can specify a visual transition, such as Fade, to control how one screen changes to another.īack and Navigate change only which screen is displayed. For example, set the OnSelect property of a button to a formula that includes a Navigate function if you want to show a different screen when a user selects that button. Use the Back and Navigate function to change which screen is displayed.
