To know how one thing is “coded”, you have to perceive what we do to the code to run in your machine. The code is written in a format readable by people, however there’s a number of optimization and adjustments which might be made to the code earlier than the machine can execute it. This course of known as compilation and linking. The results of compilation and linking code is an executable file that the machine can perceive, however people can’t. The executable that has been compiled and linked is an instantaneous code on the time it was compiled and linked. Any change within the code requires compiling and linking once more in order that the executable displays it.
This system usually must make choices primarily based on inside values ​​whereas the sport is executed. More often than not these values ​​are primarily based on knowledge, which implies that they learn recordsdata exterior the code (for instance, learn within the data of this configuration file and information it as if the sport is executed in window mode). When the sport must determine if it runs within the window mode, confirm the file, take the related knowledge and use it to determine. As a result of this data is extracting from that configuration file, the identical executable can deal with the window mode and never window. We don’t must compile and hyperlink the executable once more.
If the window mode was executed within the window, it was codified, someplace within the code itself there can be a variable like “Windowed = True”. Then, after compiling and linking the executable, that executable would at all times be executed in window mode and will by no means be executed in full display mode. The one approach to change this is able to be to alter the code, then compile and hyperlink the executable once more. Laborious coding is quick and straightforward to do as a primary step of issues, it’s a fast approach to strive issues domestically should you can compile and hyperlink the executable your self.
We can’t give the code as a result of it has copyright and our mental property. We are able to solely give the executables after compiling and linking as a result of people can’t learn them. Which means any change made within the code is kind of troublesome to distribute; That is what the patches are. Laborious coded values ​​can solely be modified after we distribute a brand new executable, whereas knowledge -based values ​​reminiscent of configuration in a configuration file are a lot simpler to alter as a result of they don’t require compiling and linking, they solely require that somebody modify the file that’s learn and never the executable itself.
