Right on!
I think I figured it out with your help. For anyone else that may encounter this problem, here’s the code I used in an Exec Script puzzle that worked for me:
// Define a function to update LED widths
function updateLEDWidths() {
// Access the slider in the parent document
var sliderValue = parent.document.getElementById(‘your_element_id’).value;
// Map the slider value ([your range of slider values (e.g. 10 to 20)]) to the LED width ([range of Area Light X values (e.g 0.45 to 0.86)])
var ledWidth = mapRange(sliderValue, 10, 20, 0.45, 0.86);
// Update the width of each Area light
var ledNames = [‘LED 1’, ‘LED 2’, ‘LED 3’, ‘LED 4’];
ledNames.forEach(function(ledName) {
// Assuming ‘app’ is your Verge3D app instance accessible in this context
var led = app.scene.getObjectByName(ledName);
if (led && led.isRectAreaLight) {
led.width = ledWidth;
}
});
}
// Helper function to map a value from one range to another
function mapRange(value, inMin, inMax, outMin, outMax) {
return (value – inMin) * (outMax – outMin) / (inMax – inMin) + outMin;
}
// Ensure this code runs after the Verge3D app is fully initialized
// You might need to place this inside a function that’s called after app initialization
updateLEDWidths();
// Add an event listener to the slider in the parent document to update LED widths on change
parent.document.getElementById(your_element_id’).addEventListener(‘input’, updateLEDWidths);
.
