Click Drag

I am having issues when i am trying to click and drag to generate a floor.

My Debug.Log is only registering the first position that my mouse is clicking on and only changing that tile instead of all tiles in the area.

Code (CSharp):

1. // Start Drag
2.         if (Input.GetMouseButtonDown(0)) {
3.             dragStartPosition = currFramePosition;
4.         }
5.  
6.         // End Drag
7.  
8.             if (Input.GetMouseButtonUp (0)) {
9.             int start_x = Mathf.FloorToInt(dragStartPosition.x);
10.             int end_x =   Mathf.FloorToInt(dragStartPosition.x);
11.             if (end_x < start_x) {
12.                 int tmp = end_x;
13.                 end_x = start_x;
14.                 start_x = tmp;
15.             }
16.  
17.             int start_y = Mathf.FloorToInt(dragStartPosition.y);
18.             int end_y = Mathf.FloorToInt(dragStartPosition.y);
19.             if (end_y < start_y) {
20.                 int tmp = end_y;
21.                 end_y = start_y;
22.                 start_y = tmp;
23.             }
24.  
25.             Debug.Log("start_y; " + start_y + " end_y: " + end_y);
26.             Debug.Log("start_x; " + start_x + " end_x: " + end_x);
27.             for (int x = start_x; x <= end_x; x++) {
28.                 for (int y = start_y; y <= end_y; y++) {
29.                     Tile t = WorldController.Instance.World.GetTileAt(x, y);
30.                     if (t != null) {
31.                         t.Type = Tile.TileType.Floor;
32.                     }
33.                 }
34.             }
35.         }

 

Code (CSharp):

1.  
2. if (Input.GetMouseButtonDown(0))
3. {
4.    if (!buttonMousePressed)
5.    {
6.       // Start Drag
7.       buttonMousePressed = true;
8.       dragStartPosition = currFramePosition;
9.    }
10.    //here you can add a visual drag 2d rectangle if buttonMousePressed is true
11. }
12. if (Input.GetMouseButtonUp (0) && buttonMousePressed)
13. {
14.    //end drag
15.    buttonMousePressed = false;
16.    //your code here
17. }
18.  

 

Thank you,

This is now telling me that buttonMousePressed does not exist in this context.

 

Code (CSharp):

1. private bool buttonMousePressed;
2.  
3. void Start()
4. {
5.    buttonMousePressed = false;
6.    //rest of your code
7. }

 

Thanks this is still giving me that same issue it is only changing the first tile that is clicked instead of the whole area that is dragged across.

this is the tutorial i am using the part i am trying to do starts at 24:14

 

Ahh... tutorials!
You need to search algorithm and then translate the algorithm into code.

I cannot help you, maybe you've skipped some lines of code.
