This is my mod for Minecraft 1.7.10 for zooming in, like how Optifine does. Z activates zoom. F and G adjust the zoom level. Note that the zoom level can only be adjusted while zoom is off (e.g. when Z is not being pressed). The keys can be customized in the Minecraft settings.
If you want to build this mod yourself, here is how I did it
First, I installed OpenJDK 8 from AdoptOpenJDK. When I installed the JDK, I told the installer to set JAVA_HOME to the correct value. This is important. If you do not have JAVA_HOME set in the installer, go back and reinstall the JDK, and tell the installer to set JAVA_HOME. I am using Windows 10.
Clone the repo. To do this, open PowerShell, and type in git clone https://github.com/CoconutMacaroon/CocomacZoomMod. Then do cd CocomacZoomMod. Now you are in the directory to build the mod. To run the mod, do .\gradlew runClient. This will build the mod from the *.java files and launch Minecraft with the mod. To build a JAR file from the mod, run .\gradlew build.
I made the mod in Intellij Idea, but you could use another editor (even Notepad, although I don't advise it). The Java files for the mod are in src/main/java/com/example/examplemod. The code has comments explaining what it does, but if you have questions or errors, feel free to raise an issue.
