Hello Unity fans and welcome back to the series. After the last few videos, recursion now allows us to find the least amount of groundwork required to place a building in a particular spot on the map, and we have an automated task system to manage builder actions. So, we can now instruct our builders to actually perform that groundwork and then construct the required buildings. We would like this construction to happen progressively to fit in with the real-time nature of the game. Let’s see how we can accomplish this.

After determining the optimal groundwork configuration, we have a list containing references to a number of cells, specifying how many elevations each needs to be adjusted by, as well as whether the small randomness built into the height needs to be cancelled. You’ll recall that we’ve added some randomness within the same elevation level to keep patches of ground from being absolutely flat. However, when a single building should overlap more than one hex, those hexes need to be forced to the exact same level, ignoring the randomness. So, we add one digging task on the centre segment to our task queue if the randomness needs to be cancelled out, and three digging tasks for each level that the hex needs to be raised or lowered by. We’ve limited this to 1 level for now, but could easily handle two levels. This means that buildings will be constructed faster on flatter land, while very uneven land may require more groundwork, taking more time to complete.
In order to let the change in elevation occur gradually while the digging is taking place, we determine how many digging actions will be required in total on each hex. Then, the digging animation triggers an event at a specific point in the animation, at which we play a sound. A group of digging cycles forms one digging action, at which point we create some dust, which will be destroyed after a few seconds, and adjust the elevation of the hex slightly. This step just calculates by how much the y-position needs to be adjusted and updates the cell’s coordinates.
Here you can see how the task queue handles these actions. If you want more detail on this, check out the video link in the top-right. What’s important for this video is the Flatten Hex method. It merely adjusts the elevation slightly each time a digging action completed and checks whether the hex has now been completely flattened. Note that we also need to change the y-position of each unit on the hex, to prevent them from floating or disappearing into the ground. Once the hex has been flattened completely, the build tasks need to be activated. We’d like to keep other units off of the building site, so we add a large movement cost to it. You may have also noted how we change the texture of the digging and building sites to a dark brown temporarily.
