Im trying to make a 2d platformer and when I added jumping I got the error “CS0131”
Could someone tell me where the issue is?

            transform.Translate(new Vector3(-2, 0, 0) * moveSpeed * Time.deltaTime);

        if (Input.GetKey(KeyCode.RightArrow))
            transform.Translate(new Vector3(2, 0, 0) * moveSpeed * Time.deltaTime);

        if (Input.GetKeyDown("space") && isGrounded = true)
        {
            GetComponent<Rigidbody2D>().AddForce(new Vector2(0f, 5f), ForceMode2D.Impulse);
        }

    }

Line 38:
if (Input.GetKeyDown(“space”) && isGrounded = true)

isGrounded == true

it needs 2 = as one = is for asigning a value.

Just to further explain, in C# a single = basically means “assign to the left side whatever is on the right side”. A double == means “are the two sides equal, true or false?” When your line starts with “if” you use double ==.

Thank you both!!

Remember: NOBODY memorizes error codes. The code is the least useful part of the error.

The important part is the description of the error itself, the file it occurred in, and the line number and character position.

All of that information is in the actual error message and you must pay attention to it.

How to understand compiler and other errors and even fix them yourself:
