Today, I've worked on level exits.
When the player arrived at the last room before, nothing awaited him. He was stuck for eternity on the same level. Kinda boring, actually...
But today this is no more! Now a big Ethernet port awaits the player at the end of the level.
He just needs to jump in it to clear the level.
I've had to create two new shaders: one that can fade the screen to black according to the player's y coordinates. I've also needed to modify my main shader to add a new parameter that can create a gradient from the usual colours to pitch black.
This way, I can simulate a bottomless pit.
