hide object on load / startUp

just place a hide object puzzle at the start of your puzzles.
then add a show puzzle to the when clicked puzzle for the object you want to make it appear.

The image below shows how I typically start a project:

The first thing are two comments:
Version of the 3D software and version of Verge3D that I am using.

The next thing is my initial procedure.
I place items in this that only need to be defined, set or initialized the very first time the application loads. In my use cases this differs from a reset function that I may have that resets the scene to the beginning similar to a initialize but doesn’t require reloading of assets.

Although the contents of the procedure could be placed outside a procedure I like to keep things tidy and not have erroneous puzzles laying about that can be executed out of the intended order so for me … everything must be in a procedure or event trigger as quicky as possible.

Inside the procedure…the first puzzle is the hide puzzle. In this example it hides the cube.
The next thing I do is define the camera (optional) and make sure the camera is at the starting location and looking at the specified item (optional). If you ever opened up the AppManager and your app and find you camera not where you expect. These are simple way to make sure that doesn’t happen.

The next item is an event trigger in this case a When clicked puzzle for the Sphere object.
It has the show puzzle that unhides the cube when the sphere is pressed.

Thats it.

Hope this helps.

There are a few approaches but this one is one of the most straight forward methods:

You can try something like this:

Just a word of advise….keep things as simple as possible- hanging or loose puzzles will be executed first so having them laying about your puzzle space and not grouped will at some point cause you grief trying to track down an offending puzzle. I also recommend putting those puzzles that you are initiallizing your scene into a puzzle…so you can control the flow of execution otherwise you have to worry about where vertically and horizontally you layout your puzzles as there is an execution order based on horizontal and vertical alignment. Needless to say that adds to the messiness of trying to debug something.

Since you want everything off and just want things to turn on when an object is clicked you can simply your puzzles down.

you actually don’t need the lightlist as I have it…its not needed but maybe something your scene required elsewhere.

Well… I think before we go round and round adding things after I supply a solution we should define all the requirements.

Is this latest twist the only addition or are there others after this that need to be considered?

KDV’s way works too.

We have all been where you are, I get it and I am glad you have started your V3D journey so welcome.

I apologize for my abruptness. Its Friday and I was trying to give you a speedy answer before heading out. Luckily this is a very simple solution with multiple right answers and hopefully you are on your way to completing your project.

So for you addition piece requesting a UI button. Did you want this to be an HTML element or 3D object. For simplicity I am going to guess a 3D element. In this case add a new 3D element to your scene or select an element you want to be your UI element and create a when clicked puzzle for it too. Inside that puzzle, just add a hide puzzle with the varialble hidelist to hide everything. If you are using the visible state variable method then add a set visible state variable puzzle to false.

If you are new to object oriented programming or programming in general this can be pretty confusing. If you find yourself in a bind you can reach me at xeons3dlab [ at ] gmail [ dot ] com.
