Javascript getting started: How do I manipulate an object instance directly?

Hi,

I am trying to get my first Construct JS scripting off the ground.

Using the default built-in script, I can easily define global vars, incrementally update every tick, and also manipulate global vars created by the visual code.

however, I tried to get an object instance and change its text, but it breaks the runtime (game freezes when I press play):

// Put any global functions etc. here
var touches = 0;
var tickcount = 0;
var jsTxto;

runOnStartup(async runtime =>
{
	// Code to run on the loading screen.
	// Note layouts, objects etc. are not yet available.
	
	runtime.addEventListener("beforeprojectstart", () => OnBeforeProjectStart(runtime));

});

function OnBeforeProjectStart(runtime)
{
	// Code to run just before 'On start of layout' on
	// the first layout. Loading has finished and initial
	// instances are created and available to use here.
	
	jsTxto = runtime.objects.jsTxt.getFirstInstance();
	runtime.addEventListener("tick", () => Tick(runtime));
}

function Tick(runtime)
{
	// Code to run every tick
	tickcount += 1;
	runtime.globalVars.globaltick = tickcount;
	jsTxto.text = tickcount; // <- this breaks it
	//console.log("tick: " + tickcount);
}


function myFubar()
{
	console.log("fubar");
}

The very first thing to do is: press F12 and look for an error message in the browser console.

It looks like it might be a bug. Can you post your project?

I am posting here per your request, also because the project is very early.

But I would prefer to send the link as a PM if possible, but clicking on your name I couldn't find a way to send private messages.

Paying customers (me) have a way to report bugs?

Well, the problem is you're assigning a number where it expects a string, which is breaking it. Make sure you convert the tickcount to a string and it should work. It looks like it's not reporting the error correctly though.

You can file bugs here: https://github.com/Scirra/Construct-3-bugs - it would be useful to post this there so it's not lost on the forum.

Oh, I see.

Being a programmer for some time, I should have thought of that - it just didn't occur to me, as I am used to implicit type coercion.

Is it because of web workers or strict mode that it broke?
