Finding the right brick for you can be the most essential part of this process. If we search on Google for “reuse with modification” for bricks or brick walls we will find a plethora of options. You could spend hours on end trying each picture out to see which one you like most, but we have another option. This is knowing what we need.
....so what do we need?
First - we need to make sure the brick is large enough and the correct shape for our game. The reason I say large is because you can always scale down and re-size once you have made your sprite and still make it look nice but if you try and scale up you will be losing quality of the picture.
Now sticking to this exact aspect is not important, because what if you want your game to have square bricks that look more like pumpkins for you to squash with your baseball bat as your guard and your baseball for the ball. It sure would make for a fun game! All you need to understand is that the 2D box collider is what matters. If we change it to a 2D polygon collider you will run into a lot of physics game changes. So for now try and keep it simple and to a box shape.
Second - we need to make sure it is not copyright protected. This is why we are taught in this lecture (Creating a 2D Brick Sprite) to search for “reuse with modification” It would be illegal for us to take just any image that someone may own if they haven't given us permission to use it.
Third - we have our brick now let us edit it! Desaturating your brick is paramount if we are using this same brick picture for all our different bricks. If you are not using the same picture for all your sprites feel free to skip this step and just remember you will have to modify each sprite or prefab individually.
Forth (& Foremost) - this lesson reminds us to keep things neat and tidy. Make folders for your sprites, prefabs, scenes and anything else you find you need. This way when we go looking for part of the project later, we can find it more easily. Don't forget to save it once you're done!
Oh! Don't forget to adjust and update as you go along! This is a step all game designers will do, it's tedious but vital to your success! I wish you good luck on your journey through this course and achieving your goals!
