I want to negate a value(multiply by -1) but the game won't allow me to type in "-1". I tried to work around this by setting an Arithmetic combinator to 0 - 1 -> N, but that just creates problems down the line. I've been trying to make it work for hours and then I found this:


This is exactly what the game won't allow me to do. Has this been changed? What do I do?

Works for me.

Does "-1" appear as you type? "Set a constant" now requires you to press Enter or click the Set button. If you close the window without doing either your input is lost.

Normally, this should work. Make sure it is an arithmatic combinator, and that you specify a constant value, not the numbered signals.

Ok I don't know why but I tried it again and it worked so... weird. Well thanks anyway
