You might have seen the news about the security exploit in games built with Unity. Both Steam and Windows have measures in place to ward off most of the danger, but each Unity game should be patched, including Trappist.

The markers for colonies and cargo ships at the edge of the screen used to clump together in the corners. Now they are better spread out which makes it easier to click on the right marker.

Some recent feedback pointed out issues in building placement. This update addresses a bunch of these and I expect the building placement to feel much better now:

• The collider of the Storage Depot has been fixed so these can be placed side-by-side now.
• The size of the Automated Storage Depot has been adjusted, so it’s still placed on the grid after rotating.
• Minor fixes to the navmesh and cargo drone path finding.
• The default keys for smooth rotation are now z and x.
• The smooth rotation speed has been increased.
• The “stickiness” of the building placeholder has been reduced.

In most city builders, the building placeholder will always be directly under the cursor. In Trappist, the placeholder collides against other buildings, which feels slightly more “physical” and “realistic” to me. Did you know that you can push cargo ships with the building placeholder?

I’ve also fixed the quality of the building outlines and removed a small stutter when the outline first appears for a building type. And there are a number of other minor performance improvements to smooth out the performance.

The demo receives the same updates as the main game build. Check out the fixes and enjoy!

The changelog for v1.0.15:

• Upgrade to Unity 6000.0.60f2.
