# Modifiers

Something that might make coding easier is to find shortcuts to represent code to set things such as coordinates where one coordinate is a 1 or -1. Then, to change the one value, multiply the variable or shortcut by a modifier. 

We've done this with speed and jumpHeight variables in different class activities, especially [Mario](/coding-for-creatives/exercises/week-6/week-6-b-2d-character-movement-unity.md).

Here are the 3D shortcuts for Unity:

| Shortcut       | Equivalent        |
| -------------- | ----------------- |
| Vector3.up     | Vector3(0, 1, 0)  |
| Vector3.down   | Vector3(0, -1, 0) |
| Vector3.left   | Vector3(-1, 0, 0) |
| Vector3.right  | Vector3(1, 0, 0)  |
| Vector3.foward | Vector3(0, 0, 1)  |
| Vector3.back   | Vector3(0, 0, -1) |

These can be multiplied and divided as an easy way to adjust the value on just one axis.
