Question Unity coordinates and positioning from JSON file

Hey! I have a task where I need to read JSON file, which consists of level_data (the coordinates where dots should be).

Code (JavaScript):

1. {
2.     "levels":[
3.     { "level_data": [ "50", "50", "950", "50", "950", "950", "50", "950" ] },
4. }

I wrote a code which takes these coordinates, but when I try to test my game, they are appearing outside my game view. The quote from the task "X and Y positions can vary from 0 to 1000. Coordinate space is centered at top left corner, so Y position is inverted (Y increases when going down). Make sure to convert positions to Unity coordinate space correctly"

This is my code:

Code (CSharp):

1.     void CreatePointsForLevel(Level level)
2.     {
3.         for (int i = 0; i < level.level_data.Count; i += 2)
4.         {
5.             float x = float.Parse(level.level_data[i]);
6.             float y = float.Parse(level.level_data[i + 1]);
7.  
8.             // Convert from your coordinate system to Unity's
9.             Vector2 position = new Vector2(x, Screen.height - y);
10.  
11.             // Instantiate a new point
12.             GameObject newPoint = Instantiate(pointPrefab, position, Quaternion.identity);
13.  
14.             // Assign the sequence number and increase it for the next point
15.             PointBehavior pointBehaviour = newPoint.GetComponent<PointBehavior>();
16.             pointBehaviour.sequenceNumber = currentSequenceNumber++;
17.         }
18.  
19.         currentSequenceNumber = 1;
20.     }

The question I ask is how to make them to appear in game view and won't be out of bounds of camera?

Thank you.

 

You need to convert from screen space to camera space https://docs.unity3d.com/ScriptReference/Camera.ScreenToWorldPoint.html

 

This sounds like schoolwork to me. Break it down like any problem.

Ask yourself a million times "Can I ....?" Just like this guy:

Imphenzia: How Did I Learn To Make Games:

In general I highly suggest staying away from Unity's JSON "tiny lite" package. It's really not very capable at all and will silently fail on very common data structures, such as bare arrays, tuples, Dictionaries and Hashes and ALL properties.

Instead grab Newtonsoft JSON .NET off the asset store for free, or else install it from the Unity Package Manager (Window -> Package Manager).
