Many people should be familiar with astarpathfinding. This is the best path finding plug-in unity3d. Whether it's 3D games or 2D games, we can use it to find the path of the * algorithm. In the previous tutorial "using free tools for 2D game development", there should have been an astarpathfindi

gradient fill. At this point, you will find that because this part has been split into a lot of small parts, stacking order is not the same, if they are grouped directly, the stacking order becomes consistent, and the change in stacking order will make our graphics change. But if you don't group, it's also very difficult to add a gradient fill to the graphic.
Here, I offer my solution, of course, your approach or more ingenious. I will select the entire graphic, using CTRL+SHIFT+F9 to

Blog reprinted from: 1871520According to Drew, the shortest path algorithm is now an important application of computer network routing algorithms, Robot Pathfinder, traffic route navigation, artificial intelligence, game design and so on. The d* (D Star) algorithm is the core pathfinding algorithm of the American Mars probe. The shortest path is calculated by calculating the minimum short-circuit calculation and dynamic short-circuit calculation. The
objects at the same time. Instead, they are added to a queue and the pathfinding process is scattered over several game cycles. If your game runs at a rate of 40 cycles per second, no one can detect it. But when a large number of Pathfinder calculate their own path, they will find that the game speed suddenly slowed. * Try to use a larger map grid. This reduces the total number of meshes searched in the pathfinding. If you have ambition, you can desi

, group the graph, and click the merge in the Pathfinder (that is, the third small icon on the left of the next row). This way, adding a gradient fill is a cinch.
Add a gradient fill and we go into the façade panel. Add a new fill to the palette and select the gradient swatch.
To modify the defect of the edge of the graph, we use the direct selection tool. At this point, you can use the
