yup yup twine 1.4x since it seems to have the coool stuff.
The if/else bit is what I'm doing for one segment of the story, it works now that I realize there's <<if else>> commands.Though it still seems kinda brute-forcey. It works for now though.
But oh man, a lot of those macros look super useful for stuff I want to do later on down the line! And omg thank you- I found info on changeing BG images, but no define answer for layered images (though it would make sence as it's html5 based)
The last one might be javascript- which would explain why I'm stumped, I saw '::' in the twinery's faq and went BWUH? 'cause I couldn't for the life of me find an explamation for the syntax, nor can I find either again ><
I'll keep looking once I get home from work though.
