Like this: public int score; And then, a way to increase it when the player does something good. Which is why its a good idea to check for it when the script is first loaded. This is especially true on mobile, where Persistent Data Path points to a public directory on the device that is separate from the applications installation. For this tutorials purpose, suppose your Player has three statistics: These are saved somewhere within your Player object. Finally, for any collision between the two collider components to be detected, I also need to add a Rigidbody 2D component to one of the objects. The player, as the moving object, with its Rigidbody and collider components, is enough to detect the collision on either of the objects. Find centralized, trusted content and collaborate around the technologies you use most.

How is an ETF fee calculated in a trade that ends in less than a year? Player Prefs can be incredibly useful for saving a single high score value. Put simply, its nothing more than a data type to store the high score values together and with it, I can begin to build the high scores list. One option is to keep all of the results (so more than ten) sort the list so that the top ten results are at the top and then only show the top ten (entries 0-9 in the list). So, instead of instantly updating the score, the number appears to count up towards its new value instead. It only takes a minute to sign up. Add a 'List<float> oldScores' to it. This involves creating a second value, the display score, that follows the real score value at a fixed rate. For example, in a side-scrolling game, where the player earns points by progressing through the level as far as they can, you might award 100 points for every unit of distance that they managed to cover.

Chances are that, unlike moving into collectable objects, the player might not actually touch an enemy to destroy it. While the list of results, as seen, can be reordered, these rows wont actually move. This allows me to set the name and score value of the entry when I create it, which makes it easier to create and manage the high score entries. Thanks for contributing an answer to Stack Overflow!
