To create the coin, we will use a 3D cylinder. Right click the Game scene in the node hierarchy ->create->3D Object->Cylinder. Name the Cylinder as “coin”.
Change the position on the y axis to 3, the z axis to -4, the y and z rotations to 90 and the y scale to 0.1 as shown in the figure.
Create a new material for the coin. Right click the materials folder->create->material. Name the material as “Coin”. Click on the material to get its properties in the inspector.
Check the “USE NORMAL MAP” option and then on the “Albedo” section, change from a white colour to something similar to gold, orange or yellow as shown in the figure.
Click on the coin in the Node Hierarchy. Go to the inspector panel and open the “Materials” section. From there, there will be a default material that gives the coin a white colour. Drag and drop the “Coin” material from the Materials folder to the Material section in the inspector. This will change the colour of the coin to the one we picked for the material.
