Modifies the velocity of the calling [Projectile](/skills/mechanics/projectile) or [Missile](/skills/mechanics/missile). In this context, it works the same as the [Velocity](/skills/mechanics/velocity) mechanic.
| mode | m | The operation to perform. Can be SET, ADD, REMOVE, DIVIDE, or MULTIPLY. | SET<!--type:Velocity_Mode-->|
| velocityx | vx, x | Velocity on the x-axis. Can be negative. | 1 |
| velocityy | vy, y | Velocity on the y-axis. Can be negative. | 1 |
| velocityz | vz, z | Velocity on the z-axis. Can be negative. | 1 |
| relative | r | If the change in velocity should be relative to the projectile's facing direction. In this instance, the `z` axis becomes `forward/backward`, `y` becomes `up/down` and `x` becomes `left/right`| true |
