Question by oh649 · Feb 26, 2012 at 03:29 AM · noobside scroller

Help with Invisibility script.

Ok I am making a 2D side scroller and I am trying to add an Invisibility effect where it turns down the player opacity but also makes it so the enemys cant see you. Right now though I am only trying to make the player go invisible. Here is my script but for some reason it wont work.

var invisible;

if (Input.GetKeyDown ("q")) { GetComponent(MeshRenderer).enabled = false; }

if (Input.GetKeyUp ("q")) { GetComponent(MeshRenderer).enabled = true; }

You need to check the keyup and keydown events every frame in order to perform any action. The Update function is called by Unity automatically each frame, so just do t$$anonymous$$s in Update, like t$$anonymous$$s:

function Update() { if (Input.GetKeyDown ("q")) { //GetComponent(MeshRenderer).enabled = false; GetComponent(MeshRenderer).material.color.a = 0.3; }

 if (Input.GetKeyUp ("q"))
 {
     //GetComponent(MeshRenderer).enabled = true;
     GetComponent(MeshRenderer).material.color.a = 1;
 }

}

You should try some basic scripting tutorials and read into the Unity docs.

edit
I changed the example. Now you need a transparent shader on your character. The colors alpha value (color.a) specifies the opacity (1.0 == 100% opaque; 0.0 == 100% transparent).
