to be entirely computer animated

[anhnha]

Toy Story(1995) was the first full-length film to be entirely computer animated.
In this sentence "animate" is a verb, therefore I think "computer" must be an adverb.
But I have just consulted some dictionaries and none of them say that "computer" can be an adverb. Could help me about this?
Thanks for help.

Hi,

As a rule, in such cases, I use the hyphenated "computer-animated", which functions as an adjective. Without the hyphen, this is harder to see.

Natives and/or cinema aficionados will probably enlighten us both.

I would use the hyphenated form too.

If it were "computer-animated" in the above sentence, I still feel confused about is it possible for an adjective modifies a verb.
Could you tell me more about it?

It still modifies "film", but "film" has been omitted in the second part of the sentece.

"Toy Story(1995) was the first full-length film to be entirely computer animated".

Consider rephrasing it if it helps: "Toy Story (1995) was the first entirely computer-animated full-length film" (yes, I know it sounds weird, but the question is: does it help to see it rephrased?)

How about an adjectival complement?
