World To Screen Point[SOLVED]

[Yanifska]

Hi everyone,

World to screen point action doesnt behave how I expected.
I feed it with a (working)world  vector3 but it won't store any screen point / X / Y.
Am I doing anything wrong ? is it a bug ?

I am trying to check what is the position of a click on the screen.
So I  have a MousePick feed a hitPoint variable and then I input this variable into the World To Screen Point action which doesnt return any screen coordinate.
I am going to try with GetMouseX/Y to fix my issue, but I am still curious to know why I am having this issue.


Any help apreciated.
Thank you
Yaniv

Hi,

 Are you not mistaking between viewport and screen reference?

http://docs.unity3d.com/Documentation/ScriptReference/Camera.ViewportToWorldPoint.html
http://docs.unity3d.com/Documentation/ScriptReference/Camera.ScreenToViewportPoint.html
http://docs.unity3d.com/Documentation/ScriptReference/Camera.ScreenToWorldPoint.html

 If in there you find what you need let me know, and I'll guide you as to how to get this with playmaker. It's important that you first understand the difference betwen screen and viewport references.

Bye,

Thank you Jean,

I learnt a thing or two in these docs, but my problem was that no value at all was stored, it stayed on 0,0. Maybe the setup of my FSM wasn't right.
Any way I moved on and find another solution.
Let's call it done for now...

Hi,

 I see. you need ot first make sure you are storing variables properly indeed.

On a related problem...

When I am converting a world point, stored in a Vector3, to a screen point, the manual indicates that the screen point value should be stored in a Vector3 format even though in is only 2D.   The issue is that the World to Screen Action IS returning a non-zero value for Z.  Is the manual wrong and I should just disregard that non-zero value?

Perhaps this is why the action won't save the information in a Vector2 variable?

Hi,

It's fine, ignore the z value. The z value is the distance from the camera ( on the camera z axis)
