Currently I finally figured out how to find a static address of ammo for a gun type, currently I have a gun's semi-automatic and am in the progress of finding the pointers for the automatic gun.

The question is how would you go about trying to find the rapid fire address? (I'm still brand new to this type, it took me around 7 hours over two days to understand pointers that go up to 8 offsets... Also no idea how to use Olly to make it!)

I've thought about attempting to slow down the game to nearly nothing and then searching for the timer between shots but I don't t think it'll work at all. I do know it's possible thought seeing as I can use the Speedhack built into to speed the firing of my gun to nearly instant.

This is a bump, the original question was figured out by me, now how would I make Rapid Fire?

Well, each gun has a different fire rate, so it has a different amount of time before you can fire again, right? So it makes sense that each time you fire, a timer is started with a certain value (either a target value, or a starting value), and either it counts up to the target and then lets you fire again, or the timer counts down to 0 before you can fire again.

If it sets a certain timeout number, then it counts down from this number. So you can fire, pause the game, and immediately search for an unknown number. Unpause and then pause again before you can fire again, and the number has lessened so search for a decreased value. Do that two or three times (with a really slow weapon) and then once you can fire again, search for 0. Then fire again and search for an increased value (since that timer went up again).

If it's the opposite and it starts the timer at 0 and counts up to a different target 'cooldown' per weapon, adjust your scanning method accordingly.

Using the speedhack setting with speedhack hotkeys set up in CE's options to freeze and unfreeze the game on demand really helps when scanning for stuff like this.

Well,
In most games (that I hacked)
rapid fire, can be found near the ammo region.
Just check +- offsets (check what writes and nop, and see if you have effect).

In the few games where I've hacked fire/attack speed, it was int because it counted game logic cycles, not seconds. Search for all types anyways to be safe.

Just use the keyboard for hotkeys. You've got one hand on it anyways.

You just need to find the address once, then you can find the code that controls it and edit the code.

If the game crashes when you attach a debugger, change the debugger settings. Use the VEH debugger for one, change how breakpoints are set, etc. It's in the CE options.

Try having it not overwrite breakpoints, and change the setting for breakpoints (virtual/physical), etc. If the game's DRM is stopping it you may need a cracked version (and the edits you develop with the crack should work on normal versions).
