And it keeps from garbage buildup

Lol, ok then, here is the physics engine The portal engine will be released with the game


(I had to remove about 1700 bytes of code to remove the portal support )

Basically you draw the level out in one big line, right to left, top to bottom.  And for level data you usually have some sections that stay the same for a bit, so you replace them with the tile type and the length of the section.  This is very very efficient for data that has large repeating sections, which levels usually do because of floors and platforms and such

Ok so i've been working on Level saving, because i wanted to make a Basic level editor to test out many different types of levels, and i didn't want to have to waste memory in level data like i am doing now.  I will be using Run-Length encoding to compress the levels (same as in Portal 1 ), and I predict an average size of around 50-80 bytes and even smaller for some of the early small and simple levels.  It will also help that levels will not be as complex (have as many floating platforms) as Portal 1 as the gameplay in general would not permit it.  As it is a portal needs at least 2 tiles next to each other in order to latch, and you have inertia, so small gaps would not be as much as a threat as they would be in Portal 1. 

As for engine development, I am working on Portal bumping currently, and moving the gun code from PxlTesting to tile testing so that tiles that do not support Portals can be implemented.  Portal bumping just means that when you  fire a Portal near a wall, it might try to stick inside the wall, but the code needs to know how to 'bump' it so that it lies fully outside the wall, or totaly on the wall.  It also need to determine when there is no room for a portal.

What would you want with Port access anyway? O.o Maybe linking?  But that i think is going to be supported in (much) later versions so i don't know.

I actualy never liked Doors The mouse interface was a bit iffy for me, hard to use without an actual mouse!

Yes, but it would be way slower and more bloated. It would translate much more easily to a few ASM opcodes.

As i see.  Well in that case get right on it Quigibo!
