Hi everyone. I'm just new/beginner to unity. I want to create a game that can move an object to specific location with an aimer and with high speed, medium speed or low speed. Like this one >> When it's turn to shoot the blue ball, there is an aiming pointer (the color blue arrow) and the velocity that can able to shoot the blue ball fast or slow. Is there any articles or tutorial that I can follow? Many thanks for reading.. Sorry for my english.
Unity has a lot of good tutorials you can follow along with. This one seems like a good place to start: https://unity3d.com/learn/tutorials/s/2d-ufo-tutorial It shows how to move an object around. It's not exactly what you're trying to do, but once you have the basic ideas in place, you can start to add Rigidbody2D to your objects and push them with AddForce.
