How to make Jedi Push and Pull objects (video)

Thank You very much! It works great! Could You translate this line into c# or something more simple? posDest = open ? posOpen : posClose;

I think the Rigidbody will be better, thanks for advice. I don't understand this code in 100% but I will read tomorrow more about Ray and ReycastHit. I understand the PushPull here: GetComponent(PushPull) is a name of script attached to cube?

Also where and how I can add a symbol which can inform the player about possibility to pull or push the object?

Thanks a lot! Cheers!

The line you indicate:

 posDest = open ? posOpen : posClose;

...works in C#. It is equivalent to:

 if (open) 
     posDest = posOpen;
 else
     posDest = posClose;

'PushPull' must be the name of the script. As for adding a symbol, how you do that code will depend on how you do the symbol. Some games use a cursor that changes. Some have a symbol that appears at a fixed location on the object (or the the object is highlighted in some way) when a raycast hit is on the object. How this works will depend on your game mechanic. You might look into using a GUITexture and using Camera.WorldToScreenPoint() from the RaycastHit to place the symbol.

Thank You very much for reply!

Could You check this code in c#? I am learning translation from JS to c# yet. It works pretty well but I'm not sure about "Send$$anonymous$$essage". Without that I have error.

using UnityEngine; using System.Collections;

 // Update is called once per frame
 void Update () {
     RaycastHit hit = new RaycastHit();
     Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition);
     
      if (Input.Get$$anonymous$$ouseButtonDown(0)) {
         if (Physics.Raycast(ray, out hit) && (hit.collider.tag == "PushPull")) {
             hit.collider.GetComponent("PushPullScript").Send$$anonymous$$essage("OpenClose");
         }
     }
 }

If I would like to send ray from center of screen I should only change Camera.main.ScreenPointToRay(Input.mousePosition); ?

Cheers!

You don't need the 'new RaycastHit()' on line 8. A RaycastHit is a struct not a class, and its values are filled in by the Raycast. $$anonymous$$ove line 9 (and 8 for that matter) between lines 11 and 12. No reason to create a ray unless the mouse button has been pressed. You are creating a ray every frame even if the user has not pressed the mouse button key. The send message should not be needed. Be sure the function you attempt to call is 'public'. Instance variables are public by default in Javascript but private by default in C#.

Thank You, good idea with moving creation of ray to if! $$anonymous$$y bad, I was only translate code without thinking :) I must be really tired... :)

With Send$$anonymous$$essage method I was fight in this way: using UnityEngine; using System.Collections;

 // Update is called once per frame
 void Update () {
      if (Input.Get$$anonymous$$ouseButtonDown(0)) {
         RaycastHit hit = new RaycastHit();
         Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition);
         
         if (Physics.Raycast(ray, out hit) && (hit.collider.tag == "PushPull")) {
             //hit.collider.GetComponent("PushPullScript").Send$$anonymous$$essage("OpenClose");
             hit.collider.GetComponent<PushPullScript>().OpenClose();
         }
     }
 }

Also method OpenClose was private - now is public. $$anonymous$$aybe in c# the name of script should be in <> ins$$anonymous$$d (). I read GetComponent<>() docs but still I can't understand how it works! :) Anyway now also I don't have any errors! I am really happy!

Cheers!
