From Emanuele Feronato: "Time to update the Phaser version adding collision detection. Yesterday in the Unity version of the prototype I wrote a script which forgives a lot of player errors, actually checking for collisions between the player and a single point of each spike.
Phaser version will be harder, because I will be checking shape collision between the player and the spikes.
How can we check for shape collision without physics? There wonÔÇÖt be any ÔÇ£shapeÔÇØ collision, we are going to check for line segment Vs circle like I did in this example.
There are only two sides of each triangle which can collide with the circle, and I am showing you when to check for collision by painting them red in this prototype:"
