Underwater effect question
I have two question actually. First is, how to I make an image effect ( motion blur ) start when I go under water and end 3 seconds after I get out and the second question, how do I add some particle effects like air bubbles only when the player is underwater? Here is my code so far:
var underwaterLevel = 9;
private var defaultFog = RenderSettings.fog;
private var defaultFogColor = RenderSettings.fogColor;
private var defaultFogDensity = RenderSettings.fogDensity;
private var defaultSkybox = RenderSettings.skybox;
var noSkybox : Material;
function Start ()
{ camera.backgroundColor = Color (0, 0.8, 0.8, 1); }
function Update ()
{
if (transform.position.y < underwaterLevel) { RenderSettings.fog = true; RenderSettings.fogColor = Color (0, 0.6, 0.8, 0.9); RenderSettings.fogDensity = 0.1; RenderSettings.skybox = noSkybox; }
else {
RenderSettings.fog = defaultFog;
RenderSettings.fogColor = defaultFogColor;
RenderSettings.fogDensity = defaultFogDensity;
RenderSettings.skybox = defaultSkybox;
}
}
I seem to recall Unity's tropical island demo had a decent underwater effect. Download the project and try it. You could then take the bits you like and use it in your game.
For image effects, you can turn them on and off by flagging 'enabled' like any other component. Therefore,
GetComponent("MotionBlur").enabled = false;
You'll do the same thing when you exit the water, except start a timer in your else condition. So...
private var timer:float = 0; if(transform.position.y < underwaterLevel) { timer = 3; // turn on everything// }
else { timer -= Time.deltaTime; if(timer <= 0) { //turn off everything// } }
