Cheat Engine

[paroxysmal]

First time poster here guys.
I have used cheat engine for around a year or two now and have had little problems searching for addresses and modifying them, and creating trainers that work as long as i don't close the game I'm playing when I create the trainer.
The problem I'm having is that the trainer doesn't work when I close the game and reopen it.

The typical way I make a trainer is I search for a value, say handgun ammo and when I find it, i enter a new value to make sure its going to work, then after I am sure I right click on the address and click 'what writes to this address'.

I attach a debugger and then go in game and shoot my handgun or pickup bullets depending on how i want my trainer to work. When I find the register that writes to the address, I add it to my trainer as handgun ammo, and click freeze amount or increase and assign it a button, lets say F1.
I save the trainer, curse at AVG for being horrid, run the trainer with the game and f1 does just what I want it to do. As soon as I close the game and reopen it the trainer does nothing.

Some codes aren't hard to find, like ammo, but other times when health/shield don't have a numeric value it is annoying to have to find these each time I run the game.

Please share with me the wealth of your knowledge and help me to find what I am doing wrong that these trainer makers do so awesomely.

Thanks

In some games, not even the code addresses are static. Check that your script is modifying the correct code before you activate it.

I read a little bit about scripts since you mentioned it.

I have very little programming background and that is what scripts look like to me.

Is there a faq or guide somewhere for script creation? I can probably figure it out if I see what I am supposed to do.

The Code Injection step of CE shows how to make a script.
