Please add more templates and tutorials on scripting

Ashley, Nepeo - first of all, thank you for this great feature!

As I understand, the main idea of scripting is to extend events, not replace them. Unfortunately, there is currently only one template (Ghost Shooter), and it doesn't provide much information on using scripting in combination with event sheets.

So could you please add more templates/tutorials for people like me not very experienced with JavaScript, demonstrating how to use scripts integrated with events. Particularly:

• When object instances are picked by event, how to pick same instances in the script. For example, I have an event "Player has LOS to Enemy", inside it a JS function "MarkEnemies()" is called, will it automatically pick the same enemy instances as the parent event?
• Different ways to pass information from the script back to events - set global/local variables, call C3 functions etc.
• How to use object's triggers, conditions and run actions from the script? For example, if I need to change Bullet angle, I should call something like Player.Bullet.SetAngleOfMotion(n) - what is the correct syntax and where can I find this action/method name?

Thanks, Ashley. I've studied the documentation. But as I said, as someone who is not very experienced with Javascript and has little understanding of how Construct 3 works internally, I still struggle trying to write my own scripts.

It would help beginners a lot if you could maybe add more code snippets to the documentation, or create a few more templates/tutorials.

All available calls are documented in the scripting reference section of the manual. However behavior calls aren't yet supported - it's on the todo list.

What about object's conditions and actions? For example, "Sprite Is overlapping another object" or "Dictionary set key" - how do I call these from the script?

There isn't any way to call arbitrary conditions/actions/expressions, and probably won't be, because as I mentioned these fundamentally rely on picking which isn't a concept in scripting. There are alternatives though, such as the method to test for an overlap between two instances, or script interfaces to access specific features like dictionary keys. These are the kinds of building blocks that the Construct engine itself is built from, and these are the same things you can use in scripting to build your game out of as well.

I agree with Doop

will be nice to have more scripting Temples to study if possible:

Example:

I'm stuck how to pick by UID

or

How to filter the picking using scripting

or

How to check an instance Boolean if is true or Check instance Variable

or

How to set a boolean to false

or

How to check if an object is Solid because has the solid behaviour

etc....

Also, I think important info like this:

Scripting has no concept of picking. That whole concept is unique to Construct's event system. However you can access the picked instances from script using the IObjectClass methods, e.g. the pickedInstances() iterator.

It should be more accessible, for example here:

construct.net/en/forum/construct-3/scripting-51/getting-started-javascript-144301

That's is the first place I went to start with the scripting.

And also I think anyone that comes from using C2 and picking, UID, etc... like me, he would like to know what is the alternative for

"Scripting has no concept of picking"

And stuff like that, because I spend many hours today looking how to pick by UID but still couldn't find it yet

Thanks for scripting, by the way, it's really Awesome to have it and is gonna be really helpful to learn to code

I currently have 2 games that demonstrate how to mix events and java script, they are not really tutorials but going through might help a bit. you can get the c3p files here

with that said It would be nice to see some more official templates integrating the scripting feature

I couldn't find any of the tutorials, have they been removed?

https://piranha305.itch.io/tanktrax has the c3p file for the tank game.

Ho Woow Thanks very much that is gonna be really helpful :)

Any chance that you know how to pick by UID?

They have it here but it doesn't say how to use it

https://www.construct.net/en/make-games/manuals/construct-3/scripting/scripting-reference/object-interfaces/iinstance

Yes so there are essential 2 ways to go about it, you either let the conditions on the event sheet pick the object for you, or you iterate over all the objects and look for the uid your looking for

here is a quick test project https://drive.google.com/open?id=1UExW5rLfhDLtEhr0nPaT7KlX-VjjMryT

it show both ways of picking, using a condition to guide your picking, and a purely picking in scripting (not sure if using the event system to pick has any optimizations as opposed to iterating over all the obejcts) but with that said you can merge both approaches pretty seamlessly, narrow down you instance list with a condition and then in JS, you can further narrow down and target the instances you want to deal, with, you can even abstract it out into a function that will return the specific set of IWorldInstances you want to deal with.

i went a bit overboard with the iterating the text input, if you know you only have one instance of sometime you can simplify it by using something

	const textInput = runtime.objects.TextInput.getAllInstances()[0];

you don't really need the first for..of loop

Ho cool no worries, Thanks for the update

Lots of good info today hope I can learn some Js quick
