Error Console
Assets/playerMovement.cs(20,63): error CS0019: Operator +' cannot be applied to operands of type UnityEngine.Vector3’ and `float’

Error Highlighted Code (C#) Line 6

if (Input.GetKey ("a")) 
		{
		//If "a" key is pressed if statement is true ---True---
			if (Input.GetKeyDown ("lshift"))
			{
				rigidbody.position += Vector3.left * PlayerSpeed + 5 * Time.deltaTime;
			}
			rigidbody.position += Vector3.left * PlayerSpeed * Time.deltaTime;
		}

This is a movement script, i want to add 5 to the current value before moving.
The lshist (Left Shift) (not sure if i got the correct text) is a sprint button so the value of the players speed will double, rather not play with the variable and set it to 10 and back to 5, i thought adding 5 if shift is pressed will work.

2 
rigidbody.position += Vector3.left * PlayerSpeed + 5 * Time.deltaTime;

should be;

rigidbody.position += Vector3.left * (PlayerSpeed + 5 * Time.deltaTime);

Ah thanks! :smile:

Input.GetKeyDown(KeyCode.LeftShift);
