Does anyone know how to remove the eye at the same time with the appearance of other eye expression, such as sad eyes or contemptuous eyes? and does anyone know where we can paste various kinds of eye expressions without having to make them?
Swap sets are designed to show one of several triggered layers, where one is the default. Pressing an "angry" trigger would then hide the default trigger. (It's the main way to hide something.)
What I find creates the least problems is to put multiple expression layers inside eyebrows, eyelids, etc. I have less problems that way than putting eyebrows inside a swap set .
Eg in left eyebrow, create a child for normal, angry, sad, happy and put artwork for each under that. Then create a swap set on the eyebrow layer. It will add triggers to each child and put them in a swap set for you. DO THIS ONCE ONLY! For the other eyebrow, create the same children, but manually drag the child layers into the existing triggers. A trigger can control many layers at once.
This way there is only one left eyebrow with alternatives inside it, rather than lots of left eyebrows per expression. Some behaviors don't like multiple layers.
There are lots of forum posts on mouths. You do swap the full set of vizemes there. Vizemes need to be directly under the tagged mouth layer I think. So that may be the exception to the above rule.
Vizemes are the ah, oh, e, m, etc mouth shapes corresponding to sounds (visual phonemes).
