Happy New Year and welcome back! This is our first update of 2015 and we hope you’ve all had a great start to your year! Here at CoffeePoweredMachine the work never stops, and we’re still chugging away on the Atlantis levels, which we first showed you in our last update.Back then, when we introduced Atlantis to you, we also talked about its ornaments and it’s foliage, and you guys gave us a lot of great feedback! Thank you very much for all your thoughts, we’re going to keep working hard on those details to make sure it look just right!
The water
The composition of the water in Okhlos is quite simple: it’s a plane.
The water is above the actual ground of the game… duh.
It’s a plane above the actual ground of the level, so the units, buildings, and enemies never interact with it. The ground is the one that posseses all the physics components, so it still handles all the collisions itself. The water is just a mesh child of the ground.
The water has a transpartent/diffuse material, and there isn’t much more to it than that. We don’t reduce the opacity of the texture, we just change it in the materials settings. This gives us much more control, and, since we’re working directly on the final look as we make changes, we can just do it all within Unity instead of having to export out a texture for every tweak we want to make.
“Agua” in spanish means water :P
As far as water within other objects goes, all the water in streams and containers was made in 2DToolkit, which makes animating it so much easier and gives us far more versatility.
As you can see from the picture above, almost all the water streams for the objects are made using sprites. We animate them frame by frame. 2DToolkit has an incredibly useful pipeline for this kind of work. We still need to export the sprites, but we change their sizes, shapes, and orientations very quickly, and we can see the results almost immediately.
This fountain has 8 different sprite animations, just to illustrate the versatility of our system.
The only real problem we had with this approach was that we had to change the material of the water within the objects to differentiate it from the water plane. The water has an Additive Vertex color material, which is why it almost seems to glow.
The cascading water, as we mentioned before, is a sprite animation, but the ripples are produced using Unity’s particle system.
It’s actually a pretty simple effect, it’s just a looping particle that throws instances every now and then.
With just a few tweaks we can apply the effect to a character. We just need to change the Emission from Time to Distance, and the simulation space to local.
The buildings
The buildings, fortunately, were pretty straight forward to make. We added some moss and a strange glowing pattern that we thought exuded a certain Atlantean look.
We added the obligatory moss, following in a looooong tradition of water levels.
As for the edges of the level, we got rid of those old fashioned mountain bases and we replaced them with water walls that have ancient Atlantean runes! So cool!
Oops… this update ended up being a little long, didn’t it? We still have at least another update to write about Atlantis, talking about enemies and hazards, but there’s also so many other things we want to talk about! We’re still not quite sure what we’ll focus on for next week, but stay tuned, it’ll definitely be exciting!
See you all next time, and happy new year!
