Wire ISF vec2 snag
Posted: Tue Jul 19, 2022 06:29
Hi! I've got a common ISF shader that works fine in ISFEditor and Magic. It won't compile in Wire.
I get five of these errors:
Thoughts on how to get this to work? And/or, thoughts on why this behaves differently in Wire?
Thanks!
I get five of these errors:
Pretty sure they refer to the lines toward the end. In those lines, the vec2 is taking two floats so I'm not sure what's wrong. (inexperienced with coding though so who knows!)Too many arguments to constructor of 'vec2'
Thoughts on how to get this to work? And/or, thoughts on why this behaves differently in Wire?
Thanks!
Code: Select all
