DiyMachinery

DiyMachinery is a physics-based building game where you use 22 basic parts to construct machines for completing obstacles, including tasks involving going over, under, hanging, climbing and bridging. There is no hierarchy limiting what you can build, so the size and complexity of your machines depend on your computer. Building and operating them calls for logical thinking, observation, manipulation and spatial imagination.

Build and connect parts

Select a blue box, choose a component from the interface and place it. Use Q, W, E, A, S, D and other keyboard keys to rotate selected components; Z removes one, while Ctrl+C copies it. To paste, select the blue box and press Ctrl+V. To weld two blue squares together, select one, click the other and press X. Welding a steering wheel disconnects the component; you can also use the button in the lower-right corner of the game.

Control your machines

You can create operating groups in two ways. First, hold Ctrl to select multiple components and click Add group; K1 and K2 controls then operate the grouped parts. For example, a hydraulic top bar rises while you press K1 and stops when you release it, with K2 working the same way. Alternatively, open the controller interface using the button in the upper-right corner, drag icons to arrange a group, select the line to operate, then use the K1 and K2 buttons in the lower-right corner. These two methods do not interfere with each other.

Wheels and slides

Front-wheel turning functions are enabled automatically. Click a wheel to open its control interface, where you can control its turning and switch its power off. Clicking the front end opens another interface for adjusting wheel suspension force and the number of turning wheels. The long slide can be adjusted to the required length by clicking its rail.

Build for each obstacle

The parts and operating methods can be combined in different ways depending on the machine you build. Obstacles require different solutions: the techniques for crossing a bridge are not the same as those for building a high-speed rail bridge.
