This repository provides a prototypical implementation of a luminance detector in Unity3D and is used for evaluation and as a showcase.
The main functionalities are listed below. A detailed description can be found in the chapter Demonstration.
- Player handling
- Input, camera, movement
- Enemy handling
- Vision, navMesh movement
- Detecting, following and forgetting the player
- Jetpack with limited but charging fuel
- Flashlight to put luminance on elements
- Luminance detection
- Install a compatible version of Unity (this repository is developed with Unity 2019.4.x)
- Notice that you may show Gizmos to easilier understand enemy behaviour
Regular jumps are executed by pressing KeyCode.Space once. Using the jetpack is executed at double jumps if the player is holding KeyCode.Space.
The jetpack has a limited amount of fuel (Force). However, it will automatically charge if the jetpack is not in use. If the fuel drops to 0 during the flight, the jetpack isOverheated. In this case, the jetpack can no longer be used until it is fully charged and the player isGrounded.
Using the jetpack may help you to get out of the field of view of an enemy faster.
The flashlight is toggled via KeyCode.F. It is used to increase the amount of light to an enemy and thus freeze it.
With gizmos you can easily understand the behavior of the opponents.
The enemy has a MaxDetectionRadius within he can become aware of the player (inner yellow line).
The player's pursuit is started as soon as he has entered MaxVisionAngle (blue lines) inside the MaxDetectionRadius.
The enemy will follow the player until he leaves its MaxReminderRadius (outer yellow line). When the pursuit is abandoned, the MaxReminderRadius is disabled and the player can approach the enemy again up to the MaxDetectionRadius.
In the graphic below you can see the enemy is illuminated by the flashlight. The amount of light emitted to him has exceeded the MaxLightLevel. He IsFreezed and can't move.
Gradually, the player moves the flashlight away from the enemy. The amount of light is reduced. Although some of the light falls on the enemy, the MaxLightLevel has been undercut. He is not IsFreezed and can move again.
With the MaxLightLevel, it is important to note that all light sources are taken into account. This results in a different total amount of light if, for example, the enemy is in the shadow and is not hit by the directional light.
The total amount of light on the enemy is calculated using a DetectLightTexture. In collaboration with the EnemyCamera, it measures all incoming light sources. For this purpose, the relative luminance is calculated using the pixels captured by the EnemyCamera using the following formula:
Y = 0.2126R + 0.7152G + 0.0722B
