Hello friends. Yesterday I finished the 5th level! It took much longer than anticipated because it’s actually 10 separate maps connected together. It includes some simple but hopefully interesting puzzle mechanics.

It also advances the story through notes and several text conversations scattered throughout.

It’s hard to see in screenshots, but I added a subtle cloud shadow effect as well. It doesn’t respond to the actual clouds, so in a sense it’s slightly faked. Because of that I was able to do the projection easily with a ray-plane intersection rather than a full matrix multiplication. Here’s the shader code, edited for clarity:

float t = -worldPosition.y / SunLightDirection.y;
float p = worldPosition.xz + t * SunLightDirection.xz;
output.lighting *= tex2D(CloudSampler, p * CloudUVMultiplier + CloudOffset).a;

Here’s the effect in action. It’s pretty subtle and easy to miss.

I already started on the next level. My plan calls for a night scene with falling water, so Thursday I worked on the beginnings of a cute little waterfall effect. It’s just a Blender model with the UVs stretched so that the texture moves faster as it reaches the bottom.

That’s it for this week. Thanks for reading!

Hey, just wanna know I'm doing a game play of it, and I'm loving this game so far. I do have a suggestion-- maybe have the secrets include some sort of collectible or achievement, or something of that nature. At the end, if you've collected enough of whatever, you get an extra cut scene and extra game play? Just something I'd like personally, though.

Here's my Quick Play (aka First Impressions) video. Though it seems to be of a slightly older build, but nonetheless, it's still a very good demo/prototype.

When I played the demo I noticed that near the end on the jungle like parkour I could jump on top of it and skip it completely, I didn't make any special ramps that I know of I just jemped around and found myself on top. The area to get on is on the right facing into the tunnel

I'm stuck because I blew all the charges to drop the fuel rod but it got stuck on a corner and now I can't do anything.

Crap. Did it get stuck on a wall you created? You could try kicking through it if so. Otherwise... you might have to reload your last save. Sorry about that.

BTW you can hit F5 to quicksave at any time.

So... development on Lemma might be kinda quiet the month of September unfortunately. I have to do some client work.

@lucyamorris Try a chiropractor? I have the same problem sometimes and they seem to help.

I've been using a growth factor of 2 for my allocators. Turns out it's a terrible idea. Great std::vector article: T.co

@djbteamsters Haha thanks! :) That's my question too. You know there's a problem when you can't answer "so what is it you do exactly?"
