A simple hydraulics mod.
v2 now has it so you can use all axles, front, back, left, and right.

How to install:
Make sure you have the latest version of GTA V.
Install latest Script Hook V by Alexander Blade (http://www.dev-c.com/gtav/scripthookv/).
Copy the "Hydraulics.asi" and "Hydraulics.xml" files to your GTA V directory.

How to use:
Press F5 to toggle the mod.
Press NumPad5 to go up on all axles.
Press NumPad8 to go up on the front axle.
Press NumPad2 to go up on the rear axle.
Press NumPad4 to go up on the left axle.
Press NumPad6 to go up on the right axle.

Customization options:
All keys. Use this website to get the hex value for the keys you want to use: http://msdn.microsoft.com/en-us/library/windows/desktop/dd375731(v=vs.85).aspx.
The up push amount.
The push amount for the front and back axles.
The push amount for the side axles.

Notes:
Some cars will jump higher than others.
Sometimes under certain circumstances you can jump REALLY high.
This mod was made for smaller vehicles, so the hydraulics doesn't really work very well on vehicles like buses, dump trucks.
This mod uses TinyXML 2 for customization.

Changelog:
v2.1:
Made it so when you first load up GTA, the mod won't be enabled. The reason I had this in v2.0 is for testing purposes, and just forgot to change it.
Added customizability for a "hold" key and a "press" key for toggling the mod. For example, Shift for the hold key and H for the press key.
Added customizability for the push amounts.
