Collider/contact functions on 2d game.
Hi everybody !
I'm making a little game with objects appearing when click. I have this code actually making things work : everytime I use the mouseclick a Gameobject is created where I click on the 2d game I created.
//Changed to an array of objects assign as many as you have in inspector
var boxes : GameObject[];
var boxCounter : int;
function Update()
{
if(Input.GetMouseButtonDown(0))//Checks to see if left mouse button was clicked.
{
CreateBox();
}
}
function CreateBox()
{
var mousePos : Vector2 = Input.mousePosition;
//Depth you want the center of the object to be is z which I used zero
var boxPos : Vector3 = camera.ScreenToWorldPoint(mousePos.x, mousePos.y, 0);
//I used the perfab box's rotation here but you can enter what you'd like as a euler using Quaternion.Euler(x,y,z)
Instantiate(boxes[boxCounter], boxPos, boxes[boxCounter].transform.rotation);
//This will increment if there are more boxes or reset to 0 if it is the last one.
if(boxCounter == boxes.length-1)
{
boxCounter = 0;
}else{
boxCounter ++;
}
}
I want to add a function to avoid the operation if there is contact/collision between the object that the function have to create and the objects already in the game. I don't know what function to use and how Is it the collider function?
Thanks in advance !
Use the OnCollisionEnter2d(), stay and exit functions like this:
//Changed to an array of objects assign as many as you have in inspector
var boxes : GameObject[];
var boxCounter : int;
var isColliding = false;
function Update()
{
if(!isColliding)
{
if(Input.GetMouseButtonDown(0))//Checks to see if left mouse button was clicked.
{
CreateBox();
}
}
}
function CreateBox()
{
var mousePos : Vector2 = Input.mousePosition;
//Depth you want the center of the object to be is z which I used zero
var boxPos : Vector3 = camera.ScreenToWorldPoint(mousePos.x, mousePos.y, 0);
//I used the perfab box's rotation here but you can enter what you'd like as a euler using Quaternion.Euler(x,y,z)
Instantiate(boxes[boxCounter], boxPos, boxes[boxCounter].transform.rotation);
//This will increment if there are more boxes or reset to 0 if it is the last one.
if(boxCounter == boxes.length-1)
{
boxCounter = 0;
}else{
boxCounter ++;
}
}
function OnCollisionEnter2D(Collision2d coll)
{
isColliding = true;
}
function OnCollisionExit2D(Collision2D coll)
{
isColliding = false;
}
The OnCollisionEnter2D() function is called when a collision takes place. The OnCollisionStay2D() function is called each frame the collision is taking place. OnCollisionExit2D() function is called when the collision stops taking place.
Hi ! Thx for your answer. But I don't see where you used the OnCollisionStay et why is there CollisionD coll in the function. Can you explain it plz?
