This is where the user will see the color they’ve picked and have “selected”. With that pixel, we use the Texture2D method GetPixel to get its color and store it in that “SelectedColor” property (line 32).įinally, we set the material color of our “preview” object to the selected color (line 34). If the ray intersects with something (line 17) and that something happens to be the color picker (line 20), then we pull the texture coordinate from the Ra圜astHit multiply it by the height and width of the texture, and get the actual pixel on the texture that we clicked. We check to see if the user has clicked this frame, and if so, we do a raycast from the click point into the scene). This is where we’ll store the users color selection when they click on the colorpicker.īut the work here is done in Update(). This script starts off with a static “SelectedColor” property.
It’s time to setup our color picker so the player can choose different colors easily.ĭrag the ColorWheel texture onto the Quad.Ĭhange the Shader to “Unlit/Transparent Cutout”Ĭreate a new script named “ColorPicker.cs” and replace the contents with this.Īdd the ColorPicker component to your “Color Picker” object in the inspector. Your PaintCanvas should look similar to this. You’ll see this later when we get into the networking code.Īdd the new PaintCanvas component to the “Paint Canvas” Quad. This is so we can ‘load’ a texture from the host when we join the game as a client.
The second thing it does is set the texture data from a byte array.
This texture is created in PrepareTemporaryTexture and assigned to the static property “Texture”. First, it makes a copy of the texture in memory so we can easily read and write to it. I”m using 1920×1080.Ĭreate a script named PaintCanvas.cs and replace the contents with this.
