Geometry Logic

In the new version of Miarmy 4.5, we can detect and feel any geometry and interactive with it. We can achieve the roller coaster effect easily.

Reference: Geometry Logic Sentence

Maya Geometry >

• I'm higher than geometry:??? distance > 0
• I'm higher than geometry:??? distance < 0
• higher geometry:??? on LEFT
• higher geometry:??? on RIGHT
• I'm on geometry:??? UPHILL
• I'm on geometry:??? DOWNHILL

Prerequirements

1. Curve Pin
2. Geometry Sentences are 100% same as Terrain, but only in different situations

Example

In below example we'll show you how to create the roller coaster by curve pin and geometry logic.

Create a geometry and a curve match the track.

Use curve pin, the agents will follow the curve, but they have wrong roll directions.

So let's create two decision nodes to fix the roll:

Now, wee get the right roll,

Under the hood

We control the agent by input geometry sentence, for left/right roll, you can use:

higher geometry:??? on LEFT

higher geometry:??? on RIGHT

With the same method, we can rotate the agent forward/backward based on the downhill and uphill:

I'm on geometry:??? DOWNHILL

I'm on geometry:??? UPHILL
