[Javascript] Character Controller + SmartJump!

Before I begin, I would like to note that I'm not quite sure which forum to post this in, so I chose the most related one.

I have written a javascript "Smart Jump" that will jump a player to the block above it [with multi-jump capability]. I also included the character controller script along with it. Here it is!:

Code (csharp):

1.  
2. //This game is block/tile-based, so each 40x40 sprite is changed with [Pixels to Units] so they are 1x1 unit.
3. #pragma strict
4. var speed = 0.05;
5. var maxJump = 3;
6. private var jump = 1;
7.  
8. function Start()
9.  {
10.  //Freeze rotation +fix z-rotation problem [player spawns and immediately collides, causing slight z rotation, but with my initiation script (spawn blocks according to position in array)]
11.  transform.eulerAngles.z = 0;
12.  rigidbody2D.fixedAngle = true;
13.  }
14.  
15. function Update()
16.  {
17.  //Check for collision in all directions [fortunately not *that* FPS intensive]
18.  var right : RaycastHit2D = Physics2D.Raycast(Vector2(transform.position.x+0.5,transform.position.y), Vector2.right,  0.00001);
19.  var left  : RaycastHit2D = Physics2D.Raycast(Vector2(transform.position.x-0.5,transform.position.y), -Vector2.right, 0.00001);
20.  var down  : RaycastHit2D = Physics2D.Raycast(Vector2(transform.position.x,transform.position.y-0.501), -Vector2.up,      0.1);
21.  
22.  //Get right-left input
23.  if(Input.GetKey("d")  !right)
24.   transform.Translate(Vector3( speed,0,0));
25.  else if(Input.GetKey("a")  !left)
26.   transform.Translate(Vector3(-speed,0,0));
27.  
28.  //Get jump input + check if exceeded maxJump
29.  if(Input.GetKeyDown("w")  jump < maxJump)
30.   {
31.   jump++;
32.   //Get the distance towards to nearest block
33.   var distance = (Mathf.Round(transform.position.y+1) - transform.position.y)+0.05;
34.  
35.   //Reset y velocity
36.   rigidbody2D.velocity.y = 0.0;
37.   //Forumla for distance jumps
38.   rigidbody2D.velocity.y += Mathf.Sqrt(distance * 2 * -Physics.gravity.y);
39.   }
40.  
41.  //Reset jump count if grounded
42.  if(down)
43.   jump = 1;
44.  }
45.  
46.  

Thanks!

|Edits->
|| 1: Slightly changed jump height +[0.01]
|| 2:Added raycast for checking if player grounded +changed raycast length
|| 3:Slightly changed maxjump code [starts at one now]

 

Thats brilliant and supersimple.

Will use this for when I need some quick controls to test with.

Thanks

 

Hmm, it must not be in the right section. Anybody knows where it is supposed to go?
