Instructions
Macro Editing Program
Download and install a macro-making programs program, such as AutoHotKey. This program will allow you to edit scripts for certain keys. There are other such programs, including Work Space Macro Recorder, Quick Macros, Macro Expert, and Macro Wizard. They all function in the same manner of scripting a single mouse or keyboard key to perform multiple functions.
Find the file called "AutoHotKey" (or other macro making program) in the My Documents or Documents folder. Right-click this file and click the "Edit Script" option. Paste the script into the window and save the file. You can find more complex scripts elsewhere, but this is a simple version:
Ins::Suspend
LButton::
Loop
{
SetMouseDelay 30
Click
If (GetKeyState("LButton","P")=0)
Break
}
Save the script and exit the file completely. Double-click the file or right-click and select "Run Script." Next time you load "Call of Duty 4," all of your shots will be rapid fire.
Disable the script after playing by fully exiting the AutoHotKey program from the system tray. Right-click the icon for the program and click "Exit."
Mouse Software Macro
Install the gaming mouse software onto your computer. Create a new macro from the macro screen in your mouse's program options. Find these options by going to the "Start" menu, select the "Programs" list, and locating the installed mouse software. When the macro creation screen appears, click off the "Start recording" option.
Copy and paste this macro into the events list of your new macro three or more times based on how many times you wish it to fire:
Left mouse down
Create delay(tenms)
Left mouse up
Create delay(15ms)
Save the macro. Load it whenever you play "Call of Duty 4." This macro will allow you to shoot as fast as your frame rate will allow.
