Hiya,

Anyone know how to make a line appear or disappear as if it was being drawn by a pen. I’ve seen this done with text before and always wondered how it was done?

Obviously theres a shape tween but thats slightly different isnt it? or can it be combined with a motion trail? Or is it a tedious case of breaking the line up into pixels and somehow making them apper or disapper in order??

Any ideas??

much apreciated.

Andy

Something like that. What you have done there can be done with a simple shape tween. Is it possible to do that with a curve using a motion trail or something?

Im not sure that masking would do what i want? Actually! - Unless a mask can be attached to a motion trail??

Hummm,

cheers guys!
