Jump as Update and as a coroutine

Coroutine.cs

bool mJumping;

void JumpCo()
{
	float jumpProgress = 0.0f;
	Vector3 jumpStartPos = transform.position;
	mJumping = True;

	while( mJumping && jumpProgress < 1.0f )
	{
		jumpProgress = Mathf.Clamp01( JumpProgress + Time.deltaTime / JUMP_TIME );
		transform.position = jumpStartPos + EvaluateJump( jumpProgress );
		yield return null; // wait till end of frame
	}

	mJumping = false;
}

Update.cs

float mJumpProgress; // [ 0, 1 ]
Vector3 mJumpStartPos;
bool mJumping;

void BeginJump()
{
	mJumpProgress = 0.0f;
	mJumpStartPos = transform.position;
	mJumping = True;
}

void UpdateJump()
{
	if( !mJumping )
		return;

	if( mJumpProgress == 1.0f )
	{
		mJumpProgress = Mathf.Clamp01( mJumpProgress + Time.deltaTime / JUMP_TIME );
		transform.position = mJumpStartPos + this.EvaluateJump( mJumpProgress );
		return;
	}

	mJumping = false;
