• VS2010 Unable to compile world

I know we had a problem with your fancy algorithms in Linux, but this is the first time I've seen another Windows box fail.

1> Combat.cpp

The EQ2TC box won't compile after the last pull from SVN. Any ideas?

btw, doesn't seem to be a problem in VS2012

Looks like floor will only take a type of "long double", "float", or "double" and we are passing it an "int8", so find the call to floor in combat.cpp and cast the params to a float, if we need the result as an int8 then cast the floor to an int8.

Example:

Code: Select all

int8 y = 0;
int8 x = (int8)floor((float)y);

Sorry, I should have posted the code too.

Code: Select all

				int8 automatic_multi = floor((int8)(multi_attack / 100));
				chance = (multi_attack - (floor((float) ((multi_attack / 100) * 100))));

It's the top line that's throwing the error, but it does this twice in this function. I thought it looked okay, but you know...

Hey, this worked!

Code: Select all

				int8 automatic_multi = (int8)floor((float)(multi_attack / 100));

Just not sure what this will do to the calc? lol
