Only proves that it uses a different sprite. You still don't have any evidence that it's actually thrown. You obviously dont get it
Undyne not directly throwing her spear Because if he made undyne throw the spear,
then it would have literally been impossible to dodge in that scene. The spear would have covered the whole box as soon as it was thrown. The attack is specifically designed to catch you by surprise once you start moving. Animating undyne throwing that spear would require him to program an entire throwing animation, move the box completely, expand the box making it easier to dodge etc. There is no way he would go through all that when he can just have you get caught by the spear.
Editing the spear out of her hand would still require another unnecessary sprite animation for him to design just for one simple surprise attack.
Mad dummy example One instance of a monster throwing an attack from their angle (which was made to be easily avoidable) does not mean every attack must be thrown from the monster in order to not be a magically spawned attack. Monsters take several different actions in fights and are not seen doing said actions through their sprites (greater dog being an example). Just because he toby is willing to sometimes make attacks come from the sprites, that does not mean every attack needs to come from a sprite in order to be a direct attack. He only programs these animations in for gags, whenever he feels like it or when the attack actually is actually fitting.
Read, your best argument is "it's different from the other attacks." Even you must realize that's not a good argument, and certainly doesn't prove the spear was thrown, especially since she's still depicted as holding the spear. Face it, your argument rests entirely on weak ground. You can't prove she actually threw that spear. You obviously dont get it.
Every other spear undyne spawns has both a different sprite and a magical spawning sound effect. The only spears undyne throws that are both aimed straight at you, fired as one, function differently from all other spears and remain silent whilst thrown is the spear in that scene, and the spear thrown in the date.
You yourself dont have anything to prove that spear was magically spawned. There is are far more similarities between the spear in that scene and the one that was thrown and the other completely differently designed spears which specifically follow the functions of the spawned ones.
Using occams razor, it requires far less speculation argue that the spear which is shown to function differently from the other spears, and more similarly to the thrown spear, was in fact thrown. And that the spears which do function differently, make the same spawning noises and function the same way as the spawned spears, are the ones which are spawned by undyne.
