In preparation for day/night cycle, i give you a easy implementation of a night system. It does not uses lights because it’s a complex and time expensive process with no good results (Trust me, i’ve done it before).

Instead we use masking, a process of masking material using shader, very easy to implement.

Import Files

• Create folder named “Shaders”, and add: LightCameraShader, LightShader
• Add file LightingCamera.cs into Scripts/Runtime/Others.

Create Materials

• Create a material called LightMaterial and on top in the inspector of the material, click the dropdown option Shader, go to Mythril2D/Light.
• Create a material called LightCameraMaterial, do the same process as before for LightShader material.

Create Light Objects

• Create a Sprite in the scene, 2D Objects/Sprites/Circle ( i recomend Circle but i’ve attached a sprite in this tutorial that has more style).
• Assign the LightMaterial to the spriteRenderer.
• In the inspector top right corner in the Layer, create a new layer called Lighting.

Setup Camera

• Open prefab 0_Hero_Base and add a child camera called LightingCamera to the already present camera. One will presenting the scene, the other only handles lighting.
• In the main camera, setup “Culling Mask” to evething EXCEPT Lighting. The LightingCamera, in Culling Mask select ONLY the Lighting. prints in attachment
• Attach the LightingCamera.cs script to the main camera, and set it’s values.

Notes:

• You can only see the light in play mode.
• To make it better, add a light to the player, so that there is always a light wherever the player goes.

Have fun!

I’ll post the day/night cycle whenever i’m finished to upgrade your game to the next level!
