getting the integer of a value.

[flyingwombat]

I have been trying to add the light mod from Tailoring and Style from UT175. I have been able to get the changes in cost, weight, and dr. I can't get the integer of the DR. I tried this

@fix(*2/3 to owner::baseweight), @fix(*2/3 to owner::dr)

and

@int(*2/3 to owner::baseweight), @int*(2/3 to owner::dr)

Help.

The "to owner::tag" needs to be outside of the maths. Try this:

gives(-@int(owner::dr/3) to owner::dr)
gives(-@int(0.4999 + owner::dr/3) to owner::dr)

The first will take 1/3 the DR, drop fractions, then subtract it from the DR. The second will take 1/3 the DR, round up, then add it to DR.

So DR 5 will result in -1 DR in the first formula but -2 DR using the second. DR 6 will result in -2 DR using either formula.

I couldn't get either formula to work. Thanks

The biggest problem here is that it will work with simple DR values, such as DR6, but not complex ones like 12/4*. GCA can read dr(6) as a numeric value and calculate from it; it cannot read dr(12/4*) as being numeric, so does nothing instead. GCA can do math to complex DR values like 12/4*, but it isn't very smart about it. Applying a gives(*2/3 to owner::dr) results in floating point errors creaping in as well as no integer rounding of DR values.

Unfortunately, I don't think that GCA is capable of applying that modifier correctly, at least not automatically.

...but I do have an idea of how to handle this is the same basic way that the Build-Your-Own armor from Low-Tech is handled.

EDIT: And I've now uploaded an updated Ultra-Tech data file to my website for your testing.

Just downloaded it. Thanks

I created a sheer set of armor. using the build it tools. It covered the character's front. The armor won't show up character sheet. I can't even apply it.

I have no issue applying the armors in the Protection Window -> Apply Armors dialog boxes. The issue I have (which is unreconsiable right now) is that GCA does not currently recognize all of the funky hit locations which the Build-Your-Own Armor rules allow you to create. "Torso" is recognized as a hit location; "Front Torso" is not.

GCA5 begins to address this, in that it can properly track all those funky hit locations. However, the UI and display of that information still needs some polishing work.

For now I will make a note of funky armor on the character sheet.
