    }

if (Input.GetKeyDown(KeyCode.E)) 
    {
        var BlockSelected += 1;
    }

if(Input.GetMouseButtonDown(0) || Input.GetMouseButtonDown(1))
    {
        var Hit : RaycastHit;
        var LookingDirection = transform.TransformDirection(Vector3.forward); 

        if(Physics.Raycast(transform.position, LookingDirection, Hit, 20))
        {
        if (Input.GetMouseButtonDown(1))
        {
        if(var BlockSelected ==1)
        {
        var GrassBlock : Transform = Instantiate (GrassBlock, Hit.collider.transform.position + Hit.normal.normalized, Quaternion.identity);
        GrassBlock.tag = "GrassBlock";
        }
        

        if(var BlockSelected ==2)
        {
        var StoneBlock : Transform = Instantiate (StoneBlock, Hit.collider.transform.position + Hit.normal.normalized, Quaternion.identity);
        GrassBlock.tag = "StoneBlock";
        }
        }
    }

    else
    {
    Destroy(Hit.transform.gameObject);
    }

}

It is expecting an initialisation i guess, due to the keyword ‘var’. Try to remove it.
Same happens few more times in your code.

It’s totally an error. You can’t use -= or += when declaring variables, and in fact you don’t want to declare variables there at all. Some additional things: I seriously doubt you want to use floats for that, and it’s easier to read the code if you stick with the convention of using lowercase for variable names; uppercase is for classes and functions.

You misspelled BlockSelected as BlockSeleted on line 6.

I had them declared at the top, but when i removed var, it fixed it… i made all my variables lowercase too :smile:… thanks!
