We will use the 0.5 version from this page : https:\/\/www.grasshopper3d.com\/forum\/topics\/maze-from-mesh but the 0.9<\/a> can be also tested.<\/p>\n

<\/p>\n

<\/p>\n\n\n\n\n\n

Set the Start Position<\/p>\n

<\/p>\n

The program name<\/p>\n

<\/p>\n

And the End position<\/p>\n

<\/p>\n

The starting point is defined. Connect Point to Position and Circle to access Radius<\/p>\n

\"\"<\/a><\/p>\n

Same with the End position<\/p>\n

\"\"<\/a><\/p>\n

<\/p>\n

Add a Boolean Toggle<\/p>\n

\"\"<\/a><\/p>\n

Pause is set in the middle of the Maze (why not). The Program is connected.<\/p>\n

\"\"<\/a><\/p>\n

Then we create the person Template<\/p>\n

\"\"<\/a><\/p>\n

We connect Start Gate, End Gate and Interrest<\/p>\n

\"\"<\/a><\/p>\n

Add Vision Angle<\/p>\n

The Person Template is set<\/p>\n

\"\"<\/a><\/p>\n

Let\u2019s Add the Ped Simulation System<\/p>\n

\"\"<\/a><\/p>\n

Connection Target to Target and Person Templates to Person Templates<\/p>\n

\"\"<\/a><\/p>\n

Obstacles are taken from the curves<\/p>\n

\"\"<\/a><\/p>\n

\"\"<\/a><\/p>\n

<\/p>\n

Ped Simulation System is complete<\/p>\n

\"\"<\/a><\/p>\n

Launch the simulation<\/p>\n

<\/p>\n

Let\u2019s a person<\/p>\n

\"\"<\/a><\/p>\n

Path is drawn<\/p>\n

<\/p>\n

We can add an Isovist simulation to represent the vision of the user<\/p>\n

Let\u2019s put a deconstruct person connected to people<\/p>\n

\"\"<\/a><\/p>\n

We will then use the decoding spaces tool https:\/\/toolbox.decodingspaces.net\/<\/a><\/p>\n

\"\"<\/a><\/p>\n

It is much more efficient than the one in Grasshopper.<\/p>\n

Grap lines from the Maze\u2019s curves include the Square as well and Explode it into segments. Flatten<\/p>\n

Grab Angle and Distances from the Person Template and connect Velocity to a Vector with viewing Direction<\/p>\n

\"\"<\/a><\/p>\n

<\/p>\n

Even with more complex Maze, the exit path is found<\/p>\n

<\/p>\n

Last step would be to have an object properly oriented that gives the direction of displacement in the Maze.<\/p>\n

Like an arrow. Let\u2019s draw an arrow <\/p>\n

The Arrow can be attached to the points but it has to be correctly oriented.<\/p>\n

When it\u2019is not it give this<\/p>\n

\"\"<\/a><\/p>\n

<\/p>\n

Orient axes<\/p>\n

\"\"<\/a><\/p>\n

It globally works, some improvements are needed.<\/p>\n

<\/p>\n

Coloring distances<\/p>\n

\"\"<\/a><\/p>\n

<\/p>\n\n\n
