I'm getting an "unspecified error" when I do certain actions with a trainer I made. The thing is, I want these errors to be ignored, and if possible not to show up at all. However I have no clue as how I should go about to doing this.

Anways the error occurs because my trainer calls a variable that hasn't been declared/initialized and it will be at a certain point of the game, which I want to change at that specific time, by having a timer running constantly calling and changing. However you get quite a few errors along the way, so is it possible to ignore these?

Also if you'd like to see what I'm doing you can see my trainer here.

The best way according to good programming practices is to simply initialize all of your variables at the beginning of the code, or a constructor in an object, to an initial default value. I haven't seen in any popular programming languages where you could declare a variable at runtime and is accessible to the global scope, so the undeclared variables shouldn't be a runtime problem.

If you're too lazy to initialize the variables to a default value, you could always use a try-catch block to catch the exceptions generated. These will depend on which language you're using and whether it supports the try blocks.

Are the variables you mentioned the variables in the swf files? Then it should be the flash object's role to handle the exceptions.

Try blocks in Delphi is actually not a try-catch, but a try-except. Here is some information:

Try a plain try-except block on the part where the error occurs.

Yeah the vars are in the .swf

Basically the game runs through a function to assign an item ID to a variable and I want to change that ID.

EDIT: So should I include an except and put nothing in its parameters? Also will this prevent the error message from displaying?

Thanks for your help, +rep, I think I can handle it from here.

Or you could've just initialized the variables to 0 on runtime... Rolling Eyes

Screw 0, initialize them as null.

It really is stupid--you have to actually SAY that it equals null, you can't just put out a variable name without a value.

I guess in Delphi, it's nil, or something. Rolling Eyes
