There is a special mechanic built in for copying values from 'custom' property elements that have types of the form ''_CustomPropertyName_#'', where # is an integer greater than zero. In this case, it is possible to set the '[[Traits|trait]]' to just ''_CustomPropertyName_'' and the engine will ''automatically'' append the current value of the property to the end. For example: | |||
<image> | |||
<user0> </user0> <!-- set by script or end user to 1,2, or 3 --> | |||
<_srcfile_1> MyMod\apple.dds </_srcfile_1> | |||
<_srcfile_2> MyMod\pear.dds </_srcfile_2> | |||
<_srcfile_3> MyMod\banana.dds </_srcfile_3> | |||
<filename> | |||
<copy src="me()" trait="user0" /> <!-- current value set to user selection --> | |||
<copy src="me()" trait="_srcfile_"/> <!-- which then determines which file --> | |||
</filename> <!-- path is actually copied --> | |||
</image> | |||
As implied by the example above, the Copy operator is the only operator that will work with string values, both as literals and copied from other string-type properties. | |||
