This trainer has been in production since 2008.
It has menu displays and sub menus (still a little buggy though).
There are also status displays for the objects/vehicles/god mode/floating, etc.
In the bottom left corner are coordinates for the player's movements.
Use f6 to turn on menu and f7 (twice) to turn it off.
Some keyboard controls are:
Page Down: God mode/on/off
Page Up: Freeze controls (use for freezing while flying).
END key: Hold it down to fly (make sure God mode is on so you don't fall to your death). When flying it is also beneficial to turn off falling by pressing Page Up (status=on).
Use the INSERT key to fix your vehicle if it is damaged.
Use the / key to move fast while flying or running.
You use the numpad keys to navigate the menus. 8/2 - up/down. Use numpad 5 to enter a selection.
Also the numpad plus and minus keys will move an object up/down when spawned.
The numpad zero and period keys will also rotate your player (a little faster than the L/R shift keys).
The multiply key will show the status of a mouse. It is not fully implemented at this time and I plan to disable it later. This was originally sneakys idea for a mouse and I just thought I'd try my stab at it too.
Use the Shift keys (left/right) to rotate your car/object, etc.
The f1 key will help you locate a player when playing online games. Hold it to navigate a list.
The f3 key will turn on fire mode (you can also use the Fire Controls menu for this).
You can make your character fly, run fast, turn invisible/reappear. You can also blow up people and create fire streams.
If you go in fight mode you will start throwing cars around. To fix this go to the Mass Destruction menu and set the radius to a lower value. Usually 100 works, I believe. Also when the game starts you can shoot at cars with a weapon sometime (or shove them) and send them flying around the screen.
A few of the options available are spawning cars/people/objects. It has teleporting and weapon selection. You can also use the cue stick.
It has speed controls for vehicles. Including a new vehicle freeze option.
It has something newer to trainers known as power modules. With these you can blow up any vehicle,person, etc and set them on fire too.
At this time the Network controls are disabled.
It has ped spawning and you can also throw people across the screen using gravity controls. It also has a Police/Swat spawner.
It has fire spawning. It also has radius controls for the fire and also for explosions. Look on my site for a special fireworks display (used by positioning an explosion in the sky.
To learn how the controls work go to Game Switches and play with the settings.
It has player selector, where you can change your character and also see names of characters before you spawn them.
These are only the minor options. There are some really powerful ones.
I originally kept this trainer very private to prevent noobs from conquering weaker players, however I don't do much online gaming with GTA 4 anything, so I left everything available to anyone now.
Some of the ideas/mods are credited to Sneakyjanit0r who helped me get started in serious modding. Also I want to thank Gtaforums for their excellent feedback and guidance.
Please note the Water controls do not work properly. They were originally developed as a beta test.
Another thing to note is the Camera controls are kind of weird and don't always work correctly.
The controls for the Animation (of your player) should be fine. My favorite is the Smoking animation.
The file has just been updated for a newer trainer release. I forgot to set the c++ option to "Release" which means the first 19 downloads won't work. It is now fixed however.
Also because of your patience you now have access to the Fighter jets seen on my channel. Make sure to spawn a helicopter and then go to Extra Options to select the jet. Then use the Vehicle Speed controls under the Vehicle Options menu to speed up the plane. Finally be sure to turn off the menus. Then use the numpad 9 key to fly fast.
I will try to create a more concise tutorial and help manual very soon.
I posted this yesterday, left for work today and came back to the site (listed below). I was in awe to see 154 downloads already.
It still needs alot of work on getting certain options to work accurately.
Also something newer to trainers is this addition will allow repeat actions more quickly on an option. Just hold down a key to cycle through a list, etc. As an example to scroll through a list of objects on the Objects List menu, just hold down the numpad 5 and it will keep moving.

Finally if anyone else wants to partner with me by sharing trainer code, email me or respond here. So far only SneakyJanit0r and I share code. However I am interested in adding Sjaak327 as a partner also. Who knows maybe we could build the next awesome trainer together.

Thanks for the feedback Kucikuc24. However keep in mind the trainer is still in the beta stages. The engine behind it works pretty well and is pretty swift.
Also guys I got so tired of waiting for gtagaming to update my recent upload that I now will have it soon posting on another server.
