Hi,
Indeed, the script can not work as is. you need to stipulate the z distance from the camera, here, it's 0, therefore where the camera is exactly, so it's not moving at all
try this script, which is the same with a new variable to define the distance from the camera.
using UnityEngine;
namespace HutongGames.PlayMaker.Actions
{
[ActionCategory(ActionCategory.Transform)]
[Tooltip("Have an object follow the mouse.")]
public class FollowMouse : FsmStateAction
{
[RequiredField]
public FsmOwnerDefault gameObject;
[Tooltip("Show the object a specific distance on the X axis, away from the mouse.")]
public FsmFloat offsetX;
[Tooltip("Show the object a specific distance on the X axis, away from the mouse.")]
public FsmFloat offsetY;
[Tooltip("Select this if you don't want the object to move off screen with the mouse.")]
public FsmBool keepOnScreen;
[Tooltip("This determines how close to the edge of the screen the object can get IF Keep On Screen is used.")]
public FsmFloat screenOffset;
public FsmFloat distanceToCamera;
private float screenHeight;
private float screenWidth;
public override void Reset()
{
gameObject = null;
offsetX = null;
offsetY = null;
keepOnScreen = true;
screenOffset = null;
distanceToCamera = 4f;
}
public override void OnEnter()
{
GetScreenSize();
DoSetPosition();
}
public override void OnUpdate()
{
DoSetPosition();
}
void GetScreenSize()
{
screenHeight = Screen.height;
screenWidth = Screen.width;
}
void DoSetPosition()
{
if (Camera.main == null)
{
LogError("No MainCamera defined!");
Finish();
return;
}
var go = Fsm.GetOwnerDefaultTarget(gameObject);
if (go == null)
{
return;
}
// get screen position
var position = Vector3.zero;
position.x = Input.mousePosition.x + offsetX.Value;
position.y = Input.mousePosition.y + offsetY.Value;
// if you want to keep the object on screen, this keeps the objects inside the screen
if (keepOnScreen.Value)
{
var xleft = 0f + screenOffset.Value;
var xright = screenWidth - screenOffset.Value;
var ytop = 0f + screenOffset.Value;
var ybottom = screenHeight - screenOffset.Value;
if (position.x < xleft) position.x = xleft;
if (position.x > xright) position.x = xright;
if (position.y < ytop) position.y = ytop;
if (position.y > ybottom) position.y = ybottom;
}
position.z = distanceToCamera.Value;
// move game object to world position
go.transform.position = Camera.main.ScreenToWorldPoint(position);
}
}
}
Bye,
Jean
