  • Hi!

    I'm trying to get into scripting, but can't figure out what I'm doing wrong here. My goal is to populate a C3 Array object using a javascript array.

    Here is my script: 

    //creating a JS array by splitting a string:
const arrayForSplitText = localVars.randomylChosenScrollText.split('.');

//accessing a C3 array object:
const a runtime.objects.ArrayFromConstruct.getFirstPickedInstance();

//This console log works as expected:
console.log(JSON.stringify(arrayForSplitText));

//Function someone here on the forums built for loading a C3 array with a JS array:
function setC3Array(c3ArrayInstance, arr){

	try {
		const w = arr.length;
		let h = arr.sort((a, b) => a.length - b.length)[0].length;
		c3ArrayInstance.setSize(w, h);
		arr.forEach((x, xi) => {
			x.forEach((y, yi) => {
				c3ArrayInstance.setAt(y, xi, yi);
			})
		})
	} catch(err){
		console.log('Errror on setC3Array function', err);

	}

}

//call the function:
setC3Array(a, arrayForSplitText)

//What I get is:
Errror on setC3Array function TypeError: x.forEach is not a function

  • Okay I simplified the code and for some reason this version works just fine: 

    const arrayForSplitText = localVars.randomylChosenScrollText.split((/(?<=[.;:])/gi));
const a = runtime.objects.ArrayFromConstruct.getFirstPickedInstance();

console.log(JSON.stringify(arrayForSplitText));

a.setSize(10, 1);

for (let i=0; i<arrayForSplitText.length; i++ ){
	a.setAt(arrayForSplitText[i], i);

}
