In this video we are going to learn how to use "change variable ... by ..." Scratch block.
This block is one of the Variables blocks, and we are going to use it to change variable values in our game.
We have learned before that variables are containers for storing some kind of values in our game.
Those values can be numbers, text,...
But not only we can store them, we can also interactively change them if we need and if they vary through the game, hence the name variable.
For example, in our game:
"game score" variable will change when we collect some points
"player health" variable will change when we touch lava or acid
...
And all of those changes we can control with this new Scratch block.

Keep on learning, keep on Scratching !!!
