unity3d : 使摄像机和玩家之间的阻挡物体透明

这里提供两个脚本，一个绑在需要透明的物体上（AutoTransparen.cs），一个绑在PLayer身上(ClearSight.cs)。

 

以下是这两个脚本。

 

1. usingUnityEngine;
2. usingSystem.Collections;
3.  
4. publicclassAutoTransparent:MonoBehaviour
5. {
6. privateShader m_OldShader =null;
7. privateColor m_OldColor =Color.black;
8. privatefloat m_Transparency =0.3f;
9. privateconstfloat m_TargetTransparancy =0.3f;
10. privateconstfloat m_FallOff =0.1f;// returns to 100% in 0.1 sec
11.  
12. publicvoidBeTransparent()
13. {
14. // reset the transparency;
15. m_Transparency = m_TargetTransparancy;
16. if(m_OldShader ==null)
17. {
18. // Save the current shader
19. m_OldShader = renderer.material.shader;
20. m_OldColor = renderer.material.color;
21. renderer.material.shader =Shader.Find("Transparent/Diffuse");
22. }
23. }
24. voidUpdate()
25. {
26. if(m_Transparency <1.0f)
27. {
28. Color C = renderer.material.color;
29. C.a = m_Transparency;
30. renderer.material.color = C;
31. }
32. else
33. {
34. // Reset the shader
35. renderer.material.shader = m_OldShader;
36. renderer.material.color = m_OldColor;
37. // And remove this script
38. Destroy(this);
39. }
40. m_Transparency +=((1.0f-m_TargetTransparancy)*Time.deltaTime)/ m_FallOff;
41. }
42. }

 

1. usingUnityEngine;
2. usingSystem.Collections;
3.  
4. publicclassClearSight:MonoBehaviour
5. {
6. publicfloatDistanceToPlayer=5.0f;
7. voidUpdate()
8. {
9. RaycastHit[] hits;
10. // you can also use CapsuleCastAll()
11. // TODO: setup your layermask it improve performance and filter your hits.
12. hits =Physics.RaycastAll(transform.position, transform.forward,DistanceToPlayer);
13. foreach(RaycastHit hit in hits)
14. {
15. Renderer R = hit.collider.renderer;
16. if(R ==null)
17. continue;// no renderer attached? go to next hit
18. // TODO: maybe implement here a check for GOs that should not be affected like the player
19.  
20. AutoTransparent AT = R.GetComponent<AutoTransparent>();
21. if(AT ==null)// if no script is attached, attach one
22. {
23. AT = R.gameObject.AddComponent<AutoTransparent>();
24. }
25. AT.BeTransparent();// get called every frame to reset the falloff
26. }
27. }
28. }
