Move character forward depending on rotation

Questions & Answers
1

I got the ray to tell when it cant move working, I have rotation working, I even have the ray rotating correctly. I just cannot think of how to get the character to move forward by 1 unit in the direction it’s facing.

if (Input.anyKeyDown)
		{
			var FowardRayDistance = 0f;

			Vector2 fwd = transform.TransformDirection(Vector2.up);
			Vector2 bwd = transform.TransformDirection(Vector2.down);

			//Foward Ray
			while (FowardRayDistance < maxFowardCheckDistance)
			{
				RaycastHit2D FHit = Physics2D.Raycast(transform.position, fwd, FowardRayDistance);
				RaycastHit2D hit = Physics2D.Raycast(transform.position, bwd, FowardRayDistance);

				if (FHit)
				{
					if (Input.GetKeyDown(KeyCode.W) && FowardRayDistance > 1)
					{
						
					}
					else if (Input.GetKeyDown(KeyCode.Space))
					{
						Debug.Log("hit: " + FHit.collider.name + "| at: " + FowardRayDistance);
					}

					FowardRayDistance = maxFowardCheckDistance;
				}
				else
				{
					FowardRayDistance += 1f;
				}
			}			
		}

The if (Input.GetKeyDown(KeyCode.W) && FowardRayDistance > 1) area is where i know the movement part will go i just dont know what to put there.

@LordBitcube, you want to move in specific direction, just multiply the direction by the distance you want to move (in your case 1 Unity unit? Then no need to even multiply) and add it to your current position.

it looks like you have already calculated forward, and assuming your not working with a Rigidbody, then: transform.position = transform.position + fwd

I am quite confused on how that works but it does. I suppose Unity just assumes when adding position forward just add by one by default.

Works perfectly though thank you so much :slight_smile:
