Therefore, the cgraphobject class isWindow Type; That is, each chart is a window; therefore, the creation of each chart should be placed in the oncreate function or oninitialupdate function; its application process, and window-type controls (such as cbutton)

The map of many 2D games is not a whole piece, but a small BMP image (such as 32x32) is spliced by arrangement, and these small images are numbered 0, 1, 2, 3, and so on. In this way, you can write a file to store a map. For example, if a map file is opened, it is like this: 111111111111111111111 110000000000000000011 112222222222222222211 112222222220000000011 113333333333333333311 110000000000000000011 112222222222222222211 Then we can use ifstrea

TTF records the text after 0x20000. A check is Japan and South Korea's uncommon words..., it turned out to be a CJK-B extension font. A dream of life .... After changing the font, I tried several small font libraries and some words would fail. Some non-existent words will be placed in the cmap table. I don't

Source = bitmap; If you don't believe it, please mark this sentence, and check if the method bitmap_imageopened will be executed. The other code above is the same as last chapter, so I wo

1. Mathematical Analysis 1) draw a straight line I thought it would be easy to draw a straight line. Just take a straight line formula and traverse X to find Y. Isn't that true. Take the 2D line as an example, because the 3D line only introduces a zcoordinate. Key problem: the straight lines we have learned in mathematics are based on the real number field. On the computer screen, the straight lines drawn are based on the positive integer domain. You

If you use Project world, you will see a coordinate error at some resolution.For example, I set the UMG resolution to 1280*720, but his (1280,720) coordinates are not on the edge of the lower right corner of UMG, that is, the UMG design frame is not 1280*720.This is because of the Ue4 resolution scaling mechanism, you can see the screen resolution and the options to fill the screen in UMG design mode, I think this is related to the player's screen resolution. There are relevant zoom options in t
