Classic Tetris like game - brick movement.

Question

Hi community

I'm in the middle of a school project and i decided to make a Tetris game 'cause it's a game everyone can relate to, but...

I've got a problem when it comes to the movement, until now I've got a script that looks like this:

var target : Transform;

function Update () { if(Input.GetButtonDown("Fire1")) { // Vector3(x,y,z) transform.Translate(1,0,0); } else if(Input.GetButtonDown("Fire2")) transform.Translate(-1,0,0); else if(Input.GetButtonDown("Jump")) transform.RotateAround(target.position, Vector3.forward, 90);

 //transform.Rotate(Vector3.right, Time.deltaTime);

}

But the problem is that i want my brick to move in the Global axis and the rotation to be the local z axis, more specific i want it to rotate around the center pivot, how is that possible? I've been looking around at other questions and tried different scripts but this one is the closest i can get.

Well i stayed up late last night so i could figure this out. I want to thank cmixco and VS48 for their fast answers. but here's what I've come up with:

'var target : Transform; var hasRotated : boolean = false; var angle1 : int = 90; var angle2 : int = -90;

function Update () {

if(Input.GetButtonDown("Jump") && hasRotated == true) {

 transform.RotateAround(target.position, Vector3.forward, angle1);
 //transform.localRotation = Quaternion.AngleAxis(90,Vector3.forward);
 //transform.RotateAround (Vector3.forward, Vector3.forward, 90);
 hasRotated = false;

} else if(Input.GetButtonDown("Jump") && hasRotated == false) {

 //transform.RotateAround (Vector3.forward, Vector3.forward, 270);
 transform.RotateAround(target.position, Vector3.forward, angle2);
 hasRotated = true;

if(Input.GetButtonDown("Fire1") && hasRotated == false) { // Vector3(x,y,z) transform.Translate(1,0,0); } else if(Input.GetButtonDown("Fire1") && hasRotated == true) { //Vector3(x,y,z) transform.Translate(0,1,0); }

if(Input.GetButtonDown("Fire2") && hasRotated == false) {

 transform.Translate(-1,0,0);

} else if(Input.GetButtonDown("Fire2") && hasRotated == true) {

 transform.Translate(0,-1,0);

//transform.Rotate(Vector3.right, Time.deltaTime);

}'

Please let me know if you see any way to optimize this script! Thanks again. - Jakob Steinn

place the actual shape into an empty game object where the shape is centered perfectly. then update the rotation/movement of the empty and voila! thats what i did for my quasi-tetris game...

myTransform.Rotate(Vector3.right, 90); //x axis
myTransform.Rotate(Vector3.up, 90); //y axis
myTransform.Rotate(Vector3.forward, 90); //z axis
