nono - lean bear, you misunderstand me!
the wings and the mosquito are one texture file, applied to a simple, flat plane. the animation is the sequence of the textures - that does not work.
a grown-out config-scripted animation would be a bit too much for such a tiny, nasty gnat IMO
for a better understanding i've put it all in a separate pbo, together with the script i'd like to use. see attachment
start the script by placing a trigger on a map, Activation: anybody, OnActivation: [] exec "\mosquito\mosquitos.sqs", then walk straight into the covered zone and the gnats should appear around you
for having a closer look at the mosquito itself put this e.g. in the onactivation field:
drop ["\mosquito\mosquito", "", "Billboard", 1, 20, [getpos player select 0 , getpos player select 1, 1], [0,0,0], 1, 1.275, 1, 0, [1,1], [[1,1,1,1], [1,1,1,1], [1,1,1,0.6], [1,1,1,0]], [0], 0, 0, "", "", "player"]
//edit: vektorboson told me that AnimationName stands for an animation class of a vehicle. so if you have a car with openable doors and drop-create it, you can thereby difine if the doors shall be open or not e.g. - if i understood him right.
