Alright, let's all take a big, long, hard, stern look at Easy #3:
The description is simple enough: Build a train bridge over an 80 meter river, using iron, steel, and two land anchors.
Of course the steel is out of the question, but fortunately this being an easy level mission, it's not hard. Just to give you a taste of what boring vanilla gameplay looks like, it's something like this:
And really, that's like the essence of engineering: Simple, efficient, effective. Doesn't even need anything more or less, cause that does the job. But we both know that's not what I'm here for, making a good bridge is easy, making a bad bridge is much harder.
I had a couple ideas, so I just went with them all:
First I have it do a dip. I want you to take a moment to compare this image with the previous one and consider how much extra detail and material is necessary just to make that little dip possible. I had to make an additional ancillary support to the middle section, I had to swap out the simple I-beam support in the middle with this complex diamond that distributes the weight more evenly, and if you'll notice, only two supports in the first picture have crossbeams, but nearly every single support in the second has them. When that train starts bouncing up and down, it just starts wrecking shit.
But let's go one further:
trains just hate climbing slopes, that was the very steepest one I could make without it 1) wrecking the whole bridge 2) stalling out mid-way. 3) Making it over, but then accelerating into the ground hard enough that it does this:
Physics on the bridge is spot on... physics on vehicles however, they'll do whatever the hell they want, up-to-and-including sinking into and phasing through the ground, so even if it TECHNICALLY made it over, it doesn't count and you gotta take that shit back to the drawing board.
It's actually pretty frustrating, because this happens the very most when you make the vehicles bounce up and down with weird slopes or wobbly/bouncy bridges, which are the most fun but it causes them to just flip out.
But moving on:
I decide that I don't need no damn land anchors, I can do fine without'em:
This is a very mundane looking bridge, but it was very exciting for me. To explain, the supports turn red and blue to indicate HOW MUCH and WHAT TYPE of force is acting on them. Turning red means that they're being crunched/compressed, turning blue means they're being pulled apart. This was exciting for me just because look how RED those top supports are! That's literally right next to breaking, I was holding my breath as the trains passed by.
But of course, I think I can do one better still:
THAT'S BETTER. Now, if you ever need to convince somebody of the ovewhelming power of triangles, feel free to show them that picture. The pushing and pulling forces being acted on each level of that pyramid are being mitigated by the layer above it, resulting in a super massive, but structurally sound modern world wonder to make the Colossus of Rhodes jealous. The only reason I didn't top it off was because that was where the skybox started.
And with that I'll say I'm done with Easy #3.
