Unity3d character name and blood bar Drawing Method, unity3d drawingThe method for drawing the name and blood bar of a person is simple, but the problem we need to solve is how to find the appropriate coordinates in the 3D world. Because the characters in the 3D world are moving, they are moving in the 3D world, not in the 2D plane, but we need to convert the 3D Character coordinates into the coordinates in

Today we will talk about the quadraticCurveTo method to draw a curve. quadratic refers to the quadratic equation in mathematics. Next we will introduce the use of the quadraticCurveTo method in detail, if you are interested, you can learn more about how to draw curves in canvas. Today we will talk about quadraticCurveTo. To be honest, this method is a little scary and can be used by function names. In other words, I think it is necessary to shorten the function name. Quadratic refers to the quad

The view component of Android is displayed mainly through three processes: mesure, layout, and draw. In the mesure stage, call the mesure (INT widthspec, int heightspec) method. The final method cannot be overwritten. In this process, the onmesure (INT widthspec, int heightspec) method is called. After the component size is set, call the final layout (int l, int T, int R, int B) method for layout. In this process, onlayout (Boolean changed, int L, int T, int R, int B) method. Therefore, the onme

The computer has brought us great convenience in life and work, which has greatly improved our efficiency. One of the computer with a "paint"-image processing, for us to simply deal with some pictures to bring convenience. The paint tool can handle picture proportions/dimensions, pixels, picture tilt angles, picture erasure features (erase unwanted parts), add text (notes) to the picture, and more. Here's a list of common features: Adjust the proportions of the picture or pixel size, throug
