Delay control Sending site: Sun and Moon Guanghua December 14, 2003 00:47:57 Sunday, site mail This is a control character customized by cterm2000 *[nM n is a positive integer representing the number of milliseconds of delay For example *[40M日*[40M月*[40M光*[40M华 Just wait for 40 milliseconds, "Day" is displayed, wait another 40 milliseconds, "Month" is displayed, and after another 40 milliseconds, the word "Light" appears. After another 40 milliseconds, the last word "华" is also displayed, before the last delay control on the screen is processed. Does not respond to user operations. Execute one by one after displaying. If some text is set to flash before the delay ends. There will be no flickering effect either Originally, only cterm supported delay control. Higher versions of sterm also provided support. There are two serious problems with this control character problem: First, fterm interprets the control character very differently. *[nM in fterm means to delete n lines from the cursor position. Therefore, it can be seen that the effect is very different. If you are using delay in qmd, please be careful not to use fixed time. Use *[M to move the cursor to the front. For example, locate the first line to cover the nickname and make a line with extension. This will have a great impact on fterm users. Delete the content of n lines starting from line 1. It will The main text is deleted, so when using delay, the effect under fterm must be taken into consideration. Each time *[M should ensure that no text is deleted. Use content. If you have to make a delayed nickname, then pay attention to positioning to the bottom of the screen each time, then use delay, and then jump. When you come back, try to use the cursor to position, such as *[23H*[40M*[1;19H Second, a long delay affects other people's normal browsing. It should be noted that *[1M does not mean a delay of 1 millisecond. The system has Response time The actual delay is much greater than 1 millisecond, so if *[M is used too much, even if the delay values ​​add up It’s not too big, but the actual delay will still be long, making it intolerable to others. In cterm2000, Edit>>System Settings>>Advanced can limit the maximum length of delay and the total length of delay in one screen. When this value is reached, the subsequent delay control is ignored, but it is an additive value rather than based on the actual delay time. Higher versions of sterm cannot limit the maximum length of the delay, but support for delays can be turned off in the system settings. You may see a delay in the essence area of ​​some BBS, which is to move to the bottom of the screen to delete a large number of lines. This is the needle. This is proposed for the set of control symbols used by fterm. However, this method is not advisable. First of all, the delay effect may not be visible. More What's serious is that for cterm users, if you delete 1000 lines *[1000M, it means waiting for 1 second, which is too long. Longer... Generally speaking, the dynamic effects that do not require the user to press any keys are all done using delay. However, there is an effect. The exception is the so-called marquee effect. It feels like a moving image, but actually uses flickering, as follows. This is not a delay This effect is created by using two adjacent full-block characters with opposite background and background colors plus a flickering effect. For example, *[0;5;31;42m *[32;41m *[m, the effect is Source: Sun and Moon Guanghua bbs.fudan.edu.cn [FROM: 10.85.24.241]
