2D (With Planes) Jump Script
I am working on a 2D platformer-type game. To achieve proper 2D, I have been using planes for characters, and then a slightly modified version of THIS script. I have got basic movement working with transform.Translate() , but I just can't achieve jumping!
This is my script for my player:
var uvAnimationTileX = 24;
var uvAnimationTileY = 1;
var framesPerSecond = 10.0;
var jumpSpeed : float = 10;
var textures : Texture2D[];
/* textures:
1 = running right
2 = idle
3 = running left
*/
function Start() {
}
function Update () {
if(Input.GetKey(KeyCode.RightArrow))
{
ChangeAnimation(0, 3, 10);
transform.Translate(Vector3.left * 4);
}
else if(Input.GetKey(KeyCode.LeftArrow))
{
ChangeAnimation(2, 3, 10);
transform.Translate(Vector3.right * 4);
}
else
{
ChangeAnimation(1, 4, 7);
}
if(Input.GetKeyDown(KeyCode.Space))
{
Jump();
}
if(Input.GetKeyDown(KeyCode.LeftControl))
{
}
}
function ChangeAnimation(arrayIndex : int, frames : int, fps : int)
{
uvAnimationTileX = frames;
// Calculate index
framesPerSecond = fps;
var index : int = Time.time * framesPerSecond;
// repeat when exhausting all frames
index = index % (uvAnimationTileX * uvAnimationTileY);
// Size of every tile
var size = Vector2 (1.0 / uvAnimationTileX, 1.0 / uvAnimationTileY);
// split into horizontal and vertical index
var uIndex = index % uvAnimationTileX;
var vIndex = index / uvAnimationTileX;
// build offset
// y coordinate is the bottom of the image in opengl so we need to invert.
var offset = Vector2 (uIndex * size.x, 1.0 - size.y - vIndex * size.y);
renderer.material.SetTexture("_MainTex", textures[arrayIndex]);
renderer.material.SetTextureOffset ("_MainTex", offset);
renderer.material.SetTextureScale ("_MainTex", size);
}
function Jump()
{
}
But what would go into that Jump() function?
Thanks in advance.
Neither, as the player only moves along the x axis. Would I need one to use the y axis properly? Or could I get away with using another transform.Translate() in some way?
