Rotation

Everything about Rotation and how it works with the Pattern asset and the GameplayTask.

Base Grid Orientation

To understand the how rotation works, you need to know how the grid is being oriented.The grid pattern is automatically rotated 90° clockwise from its authored layout to align with character movement:

• Grid “Up” direction → Character Forward direction (Yaw 0°)
• Grid “Right” direction → Character Right direction

This ensures that when you design a pattern pointing “up” in the grid editor, it will cast forward from the character in the game world.

Rotation Axis

The axis around which the pattern spins.

Common Rotation Axes:

• Vertical Spin: (0, 0, 1) - Pattern spins like a ceiling fan (horizontal rotation)
• Side Roll: (1, 0, 0) - Pattern rolls left/right like a wheel
• Forward Roll: (0, 1, 0) - Pattern tumbles forward/backward
• Custom Diagonal: (1, 1, 0) normalized - Creates unique spinning effects

Rotation Speed

GridCast doesn’t have a tick. This is not degrees per second, it is degree per step. When you apply Rotation of 15 and -15, every next step in the pattern will have the rotation apply to them. It’s much clearer once you see it happen below.

WARNING

The first step in the pattern’s execution will not have any rotation applied to it. If you have a single-chain pattern and you set the mode to full-burst or chain sequential, then this rotation will do nothing.

WARNING

This doens’t working with full-burst processing type.
