Help for tactical movement needed !

Hello, I am new at C# and I need help to make a script that:

- detects when I click within the 2D polygon collider of a sprite renderer that is a child of a character mesh (so it allays follows it).

- then if I clicked in on the collider it moves my character where I clicked, but if I click outside the collider it doesn’t move.

- given a parameter of “MovementPoints” the 2D polygon collider of a sprite renderer also grows/shrinks.

- given a parameter of “Movementpoints” it detects how much are used based on the distance traveled and stores the information


So far I got the click to move part but I can’t make it constraint only to the collider. My final goal is for that to be the movement system of a turn based tactical game. If there is a better way to do this I am open to suggestions. but for now here is my script:

Code (csharp):

1.  
2. using System.Collections;
3. using System.Collections.Generic;
4. using UnityEngine;
5. using UnityEngine.UI;
6. using UnityEngine.AI;
7.  
8. [RequireComponent(typeof(PlayerMotor))] // here I deal with the player agent for the nav mesh
9.  
10. [RequireComponent(typeof(PlayerStats))] // the movement points come from here
11. public class TacticalMovement : MonoBehaviour {
12.  
13.  
14.     public LayerMask movementMask;
15.  
16.     Camera cam;
17.     PlayerMotor motor;
18.     Ray ray;
19.     SpriteRenderer walk;
20.  
21.     void Start () {
22.         cam = Camera.main;
23.         motor = GetComponent<PlayerMotor> ();
24.     }
25.  
26.     void Update () {
27.         if (Input.GetMouseButtonDown (0)) {
28.  
29.             Ray ray = cam.ScreenPointToRay (Input.mousePosition);
30.             walk = GetComponent<SpriteRenderer>();
31.  
32.  
33.             RaycastHit hit;
34.  
35.             if (Physics.Raycast (ray, out hit, 100, movementMask )) {
36.  
37.                 MeshCollider walk;
38.  
39.  
40. if (walk = hit.transform.GetComponent<MeshCollider> ()) { // here I tried to add a second check for the mouse hit on the colider
41.  
42.  
43.  
44.  
45.                     motor.MoveToPoint (hit.point);
46.  
47. }
48.  
49.                 }
50.  
51.  
52.  
53.             }
54.         }
55.  
56.     }
57.  
58.  

PS: I don’t know yet how exactly I will indicate the equivalent movement per 1 MovementPoint, perhaps via multiple transparent layers that stack on each other and there is a layer 1,2,3… etc. for each MomentPoint, but that seems like a crappy solution and the goals above are much more important to nail right.

 

Use code tags. Check the first thread in this forum.

 

First off, you should use the code tags to make your code easier to read. There's a stickied thread about how to do that.

Secondly, you're on the right track with what you've written so far. You need to use "==" instead of "=" in your second if statement though. If you've got a bunch of different colliders you want to use, you'll need to check against all of them. You can do this using a "for" or "foreach" loop, and you can get the different colliders of your parent by using GetComponentsInChildren.

I'm not sure I understand your other questions.
