EZ Math Movie, Tutorials, Input and Output, Showing and Hiding


Making gizmos invisible

Any input can be made invisible by calling the appropriate command as shown in this code:

// Hide input gizmos.
hide1stInput();
hide2ndInput();
hide3rdInput();
hide4thInput();

And the output gizmos can be made invisible with these commands:

// Hide output gizmos.
hide1stOutput();
hide2ndOutput();
hide3rdOutput();
hide4thOutput();

If you wanted to hide some of the unused input or output gizmos in your program, you could place these commands in the before loop code.

Making gizmos visible

The following commands will make an input gizmo visible:

// Show input gizmos.
show1stInput();
show2ndInput();
show3rdInput();
show4thInput();

Output gizmos can be made visible with these commands:

// Show output gizmos.
show1stOutput();
show2ndOutput();
show3rdOutput();
show4thOutput();

By default, if you start with a fresh and complete EZ Math Movie interface, all input and output gizmos are visible.

Running the example program

The example program is a simple calculator that accepts the lengths for the base and height of a triangle and then outputs the area of the triangle.

Not all of the input or output gizmos are needed for this job, so the unused ones are hidden.
