WiMi5 integrates a powerful visual scripting solution based on Blackboxes that allows you to create the logic flow of the game. You don't have to code (if you don't want) but you can also do it. WiMi5's actions and behaviors resemble flowcharts where each box represents a function or value, with connections between them representing program flow. This provides a better at-a-glance indication of game logic than a simple list of events, and makes complex behaviors easier to accomplish.
