Questions... A lot of questions...

Hello.

I just throw some questions in here. These were the Top15
that first came to mind. I don't expect all of them to be
answered but it would already help to know the answer to some of them.

I do not necessarily need a thorough explanation,
just some hints or pointers to some functions might be enough.
If I then need a more in-depth explanation I can ask more specifically.

I think I might be able to find out some of the answers myself,
but searching for every single one of these and rely on trial and error is just too much for me.

So here we go:

1) I find no "spawn" method in the API. How do I spawn an object? (Like enemies)
How to spawn randomly in a predefined area? (like a bounding box area)

3) How to check for a collision with a specific object/type of object?
(Collision Filtering)

4) How to remove/destroy/hide an object

5) How/where do I to store persistent game data when unloading/loading new scenes? (Like remaining lives & score)

6) What is the best approach for saving persistent data to disk (like high score / high score table)

7) For Builder there are hotkey shortcuts for bevel and extrude but these are not in the roll bar menu? why?

8) How to set up spawn points for checkpoints/player progression?

9) How to do Camera lerp/camera lag for better/smoother look

10) How to switch between different cameras?

11) Sensor. How to get the trigger data/info? How to work with it?

12) Are there anywhere example projects that actually have a bit more practical game code?
(Not only demo scenes that only show one specific thing in isolated cases)

13) Can someone provide actual game code examples that show how to work with various methods from the API? I tried Github but there are exactly 0 results for the current version of NeoAxis.

14) How to do/animate emissive material?

15) I found nothing anywhere about Lighmaps baking / Global Illumination etc. So I think it's not available?

EDIT: Bonus: Delta Time. I only managed to find NeoAxis.Time.SimulationDelta.
I can't imagine that this is the correct way to work with delta time though?
In example, I saw EngineApp.EngineTime but I am not sure if this should be used to calculate deltaTime?

Thanks in advance for every single question answered.

Hello,

To add collision to the object use Scene Editor tab, Add Collision button.
To call ray, volume casts for scene objects. Find an example in the NeoAxis.CoreExtension project. Find by "Scene.GetObjectsInSpace( getObjectsItem )". There are two examples: for ray and for bounds.
To call ray, volume cast for physics objects. "scene.PhysicsRayTest( item )".

Use Objects property to get current list of the affected objects.

Use ObjectEnter and ObjectLeave to get updates of the affect objects, or override OnObjectEnter and OnObjectLeave methods in a derived class.

To refine the filtering, you can create a handler for the FilterObjectEvent event, or override the OnFilterObject method in a derived class.

Click F7 to change free camera in the Player.
To control camera settings use event GetCameraSettingsEvent of the Game Mode component.
To change camera from the code use scene CameraDefault property.
