Hello! I am new to Phaser and so far are loving this engine. To learn how to develop with the engine I decided to try to recreate a Doodle Jump style game and have come across two questions: The first one: is it possible to disable certain types of collisions but not others? By this I mean, if you recall Doodle Jump, when the sprite touches the bottom of one of the platforms it doesn't interact with it, but when it lands on top of one, then the sprite jumps, so it continues to go up the map. I cannot figure out how to do this. I know that with Phaser I can detect certain types of collisions by using 'touching.down' and 'touching.up', but what i have tried hasn't worked. My second questions is: I want to use the gyro or accelerometer to make the sprite move. I was wondering if someone could point or show me a very simple example of taking information from these sensors to make a sprite move. Thank you.
