Hey guys, is there anyway to parse a value? This is my problem

There is an instruction to convert integer into float (fild), but it won't work the opposite way. If you want to make calculations with the value, you will have to use it as a float value (use fadd, fsub, etc). And if you replace an integer with a float value, the result will be gibberish, because the program will still handle it as integer.

The value on 0000 offset is 0, so CE will have a hard time predicting what should be the value type. It could be float as well, 0 is 0 both in float and integer.

Offset 0 contains the current ammo in a clip, so I know that is a 4 byte. I know offset C is the max clip ammo because I've checked that offset for all guns and offset C is always the value of which the gun reloads to. So I'm assuming this can't be done? Thanks anyway

Just because CE says it's a float value, doesn't mean that it's actually a float value (or vice versa). Double click on it and change the value type. You can use whatever value type you want in your script. Some may not work correctly, depending on what the value represents. In this case, since the value represents ammo quantity, using 4 byte type or similar should work. If not, and it actually is float type, then use float.

yup checked it, actually is a float

If current ammo at +0 is 4 byte, then max ammo at +C should be the same. If max ammo at +C really is float, then current ammo at +0 should also be float (so change it). I find it hard to believe that the game uses different data types to represent ammo.

Have you even written a script and tested it? At this point, I don't see the problem.

yea I tested it, I checked the 4 byte value and float value for both offsets and they are the correct type as they appear on the table, I wrote a script to push +C and then pop +0 and I got some huge number so that didn't work out.

vng21092- how do you know what value type they are?

Anyway, if what you're saying is true, then you probably do not have the correct offset(s). Your current ammo offset may be correct, but the maximum ammo offset may not be etc. Regardless, you can still move +C offset as float in to current ammo...you will just have a large number. If you do not want that, use a custom value, or, find a different offset.

To answer your original question...

There is no conversion process required. Float 8.0 is 1090519040 in decimal and 41000000 in hex.

That said, if you want to convert the text (e.g. 8.0) and have the script write it as 4 byte, then you could probably do this with LUA.

Yes. And I know. Very Happy

Never learned LUA script before, but I'll pick it up sooner or later, thanks for the help guys.
