๐Ÿ’  1. Introduction

Imagine that you make car running along curved road in Unity Scene.

You can make this car with Animator, but there are some problems.

<br>

๐Ÿ”ถ 1-1 . It is difficult to handling object between keyframes.

image

Assum the object will move from red squre to blue squre.

There are so many ways to move object.

But If you implement this with Unity Animator, the Animator will choose the shortest path (orange line).


๐Ÿ”ถ 1-2 . It is difficult to move at a constant speed

image

Suppose there is a path moving from a red square to a blue square through a green square as shown in the picture above.

When the distances of each point are not equal, if the animation keyframes are distributed as follows 1:1

image

The speed at which the object moves in the two sections is different.

So, if you want to make constant speed animation when s1 and s2 are not equal,

you should control keyframes to become S1 : S2 = ( t1 - t0 ) : ( t2 - t1 )

Of course, It's possible if you spend a lot of time.

But if the path is curved, It will be very hard to calculate the ratio.


๐Ÿ”ถ 1-3 . Bรฉzier Curve

The common issue of problems 1-1 and 1-2 is'curve'.

I was looking for how to express curves in Unity, and I found something called Bezier curves.

bezier-curve 01

First, think of a point that moves a straight line.

There is a straight line and the point M is moving at a constant speed above it.

The trajectory of this point M is drawn as a simple straight line.

At this time, t is a number indicating how far the line segment has been proportionally advanced.

Add another line here and place a point on it that moves like an M.

Then, the original point M is referred to as M0, and the new point is referred to as M1.

The rules for moving M0 and M1 are the same as before.

bezier-curve 02

Here you can draw one more line connecting M0 and M1.

The line naturally moves together when M0 and M1 move.

You can put the point on that line, and let that point be B.

And if you look at the trajectory drawn by point B, you can see that it becomes a curve drawn at a constant speed.

The trajectory drawn by point B is called a quadratic Bezier curve.

Below is the Bezier curve equation for time t.

image

As you increase the control point, you can create a 3rd, 4th, 5th order .. Bezier curve.

As the control point increases, you can create sophisticated or complex curves,

For this project, I thought that the quadratic Bezier curve was sufficient.

<br><br>

๐Ÿ’  2 . Environment

Unity Version : 2019.4.1f โ†‘

<br><br>


<br><br>

๐Ÿ’  3 . How to use

There are 2 scripts I will introduce.

So let's get started.

<br><br>


<br><br>

๐Ÿ”ถ 3-1 . Package import

3-1-1 . You can download the latest released unity package or download this repo.

3-1-2. Import Unity package.

However, the following must be observed.

<br><br>


<br><br>

๐Ÿ”ถ 3-2 . Generate Path

๐Ÿ”น 3-2-1 . Object creation

Create an empty game object in your scene. (And rename it to "Path".)

This object becomes a curved path that can be followed.


๐Ÿ”น 3-2-2 . ์ปดํฌ๋„ŒํŠธ ์ถ”๊ฐ€

Add Path Generator component to this object.

figure8

Path Generator is largely divided into 6 parts.

CategoryDescription
Header partDetermine the nature of the path.
Node partShows a list of nodes that determine the origin, waypoint, and destination.
Angle partShows a list of angles that determine the shape of the curve.
Full Control PartAll nodes and angles can be collectively controlled.
Rendering partCreated curves can be visualized.
Editor-related partsEditor settings for easy curve control

<br><br>


<br><br>

๐Ÿ”˜ 3-2-2-1. Header part

The part that determines the nature of the Path.

figure22

3-2-2-1-1. Path Density

``Path density```` determines how accurately the curve is drawn.

figure11

The higher the number, the closer the curve is to the ideal, but too high and the object may behave erratically.

Important point, Path density must always be greater than or equal to 2!

Recommended values are 30-50.

3-2-2-1-2. Update path in runtime

If the Update path in runtime item is True, the path is updated every frame.

Through this, even if the path changes in runtime, it is applied immediately.

However, the amount of computation may increase.

3-2-2-1-3. Change to closed/opened path

Determines whether to connect the last node and the last node.


๐Ÿ”˜ 3-2-2-2. Node part

Shows a list of nodes that determine the origin, waypoint, and destination

figure23

3-2-2-2-1. Create node

Adds a node to the end of the list.

3-2-2-2-2. Delete node : [-] Button

Remove the selected node.

3-2-2-2-3. Edit node : Edit Button

Edit the selected node.


๐Ÿ”˜ 3-2-2-3. Angle part

Shows a list of angles that determine the shape of the curve.

figure24

3-2-2-3-1. Edit Angle : Edit Button

Edit the selected angle.


๐Ÿ”˜ 3-2-2-4. Full Control Part

All nodes and angles can be collectively controlled.

figure33

3-2-2-4-1. X / Y / Z to 0

Set the X / Y / Z values of all angles and nodes in this path to 0.

3-2-2-4-2. X / Y / Z equalization

Average the X / Y / Z values of all angles and nodes in this path.

3-2-2-4-3. X / Y / Z to specific value

Make the X / Y / Z values of all angles and nodes in this path a specific value.


๐Ÿ”˜ 3-2-2-5. Rendering part

You can visualize the created curve as shown in the figure below.

figure30

There is a bug where the rendering is not displayed normally when the curved path is sharply bent.

figure25

3-2-2-5-1. Generate path mesh in runtime

If Generate path mesh in runtime is set to True, create a mesh that can visualize the created curve.

3-2-2-5-2. Texture of line mesh

Texture of the mesh of the lines to be displayed.

If the texture has a pattern like the picture below, it is good to express the flow.

<img src="https://github.com/KimYC1223/UnityPathGenerator/blob/master/ReadmeImage/figure27.png?raw=true" width="256px">

Demo textures located at /Assets/PathGenerator/DemoScene/Textures/

If you want the texture to repeat, you must set the Wrap Mode to Repeat.

figure26

Also, if you want to see the Material repeated in the Scene,

figure28

You need to turn on Animated Materials.

3-2-2-5-3. Width of line mesh

The width of the line mesh to be displayed

3-2-2-5-4. Scroll speed

Scroll speed of the line texture to render. Can be set from -100 to 100.

3-2-2-5-5. Opacity

Transparency of the line texture to be displayed.

3-2-2-5-6. Filling

Decide how far to draw the line mesh to be expressed. Can be set from 0 to 1

3-2-2-5-7. Render queue

Specifying the render queue order of materials


๐Ÿ”˜ 3-2-2-6. Editor related parts

Editor settings for easy curve control

figure29

3-2-2-6-1. Normal mode

This mode changes the Transform information (Position, Rotation, Scale) of the current object.

This mode appears when an object is selected in Unity.

3-2-2-6-2. Individual

This mode allows you to edit the position of nodes and angles, not the current object.

Each node and angle can be edited one by one.

3-2-2-6-3. Total

This mode allows you to edit the positions of nodes and angles as a whole, not the current object.

Selecting this mode allows you to control all nodes and angles at once.

This can be useful when resetting the pivot of the path.

3-2-2-6-4. Show labels

If this option is True, the label is visible in the scene.

3-2-2-6-5. Show icons

If this option is True, the icon is shown in the scene.

3-2-2-6-6. Change to top view mode

You can switch to Top view mode looking down the scene from above.

3-2-2-6-7. Guideline colors

You can specify the color of the guidelines.

<br>

๐Ÿ”น 3-2-3 . Create a path

Use the above functions appropriately to create the path you want.

figure31

<br><br>


<br><br>

๐Ÿ”ถ 3-3 . Move Object

๐Ÿ”น 3-3-1 . Create object

Add an empty object to move.

This object becomes the object following the path created in 3-2.

๐Ÿ”น 3-3-2. Add component

Add a "Path Follower" component to that object.

figure32

Path Generator is largely divided into two parts.

CategoryDescription
movement information partdetermine the nature of the movement.
event partDefines an event that occurs when a path is completed.

<br><br>


<br><br>

๐Ÿ”˜ 3-3-2-1. movement information part

Define the characteristics of movement.

3-3-2-1-1. Path

Specifies the path to move. Just select PathGenerator in Scene.

If Path is empty, Path Follower cannot be moved.

3-3-2-1-2. Speed

Specifies the movement speed.

The object moves along the given path at this speed.

If you enter a value that is too fast, it may malfunction.

3-3-2-1-3. Distance threshold

When the distance between the moving object and the next node becomes less than this value,

It determines that the object has arrived at its destination and moves to the next node.

If this value is too small or too large, it may malfunction.

3-3-2-1-4. Turning Speed

is the rotational speed of the object.

3-3-2-1-5. Is Move

If this value is false, the object does not move.

3-3-2-1-6. Is Loop

If this value is true, the object will repeat its path infinitely.

It doesn't matter if the path is closed or open.


๐Ÿ”˜ 3-3-2-2. Event part

Defines a method to be executed when the route is completed.

3-3-2-2-1. Execute a method

If this value is true, the method is executed every time the route is completed.

At this time, if object's Is Loop is true, the method is not executed forever.

(Because I don't think I've completed the route.)

<br> <br>

<br><br>

๐Ÿ’  4 . Examples

๐Ÿ”ถ 4-1 . Auto Driving

There may be many examples, but the best example is to create an object that runs along a given track.

figure15

I once made a car that runs on a circular track I got from the Asset Store.

figure16

With a little modification, you can implement a car that moves naturally even the wheels and steering wheel.

<br><br>


<br><br>

๐Ÿ”ถ 4-2 . Planet Movement

figure17

You can express movements between planets like the solar system.

This script also allows you to create circular paths and elliptical orbits like Comet Halley.
