Proof that a player can fly in Skyrim well may be more like swimming

[porroone]

Well if you do not call a registerForUpdate(x) the OnUpdate event wont run, still I wouldnt advise to use it, use a loop instead, im not sure which version of my script are u using, I have several on different pages, look for the last one, thats the good one.

As far as performance though, I would put in a Utility.Wait(0.001) somewhere in the script so that the interpreter sees it as a latent function. (Do not use a wait time of 0 seconds, according to the wiki page.) I've gotten some crashes when this has not been done. Edited March 11, 2012 by jimhsu

I mixed your code with my own.

The gravity adjustment works. The toggle works. The shader works. The only thing not happening is the translate and I can't figure out why.

                Fly()
           endwhile
       elseif Caster.HasSpell(DVampireBatFormToggle)
           Caster.RemoveSpell(DVampireBatFormToggle)
                       
                       Caster.SetAlpha(1)
                       DVCelerityShadow.Stop(Caster)
                       Game.GetPlayer().SetAllowFlying()
                       Utility.Wait(1.0)
                       ;bVal = False
       endif

 

Your while condition is inside an If block who's condition is opposite.

 

If ! Caster.hasspell blah blah

 

while Caster.hasspell blah blah

 

end while

 

end if

 

The while never ever gets called in that if case.

 

edit: I see you add the spell... set up a debug to make sure the while is being run. Your code makes sense in line, but opposing conditions like that are a red flag to me that you might be having some issue with the scope of Caster. My theory may still be right depending on how Papyrus was made, but I don't think the scope rules are documented anywhere.

 

 

Re-edit: Second possibility. You may not be assigning the player object to your player property in the creation kit.

 

As a note this code uses GetPlayer(), Game.GetPlayer() (same thing i know), one Player Property, one local Player as an ObjectRef (Never useful unless you need to pass Player as an ObjectRef), as well as multiple event variables that are ALWAYS the player. PICK ONE!

I was messing around with the TranslateTo options to add 'flight' to my mod, but you'll clip through things.

Then I tried the havok impulse generation. It won't work; you get ragdolled and can't control the direction.

 

What I think WILL work:

1) spawn anobject that's about the size/shape if the player, but transparent

2) apply the impulse to this new non-player object, based on the player's angles

3) TranslateTo the player towards the now flying object

 

No need to mess with gravity either. Landing might hurt though.

 

* 'Flight' is in quotes because I'm thinking of something along the lines of the Fizzy Pop from the first Willy Wonka movie.

No updates on the "Havok Behavior" situation?

Here's my first step. The bucket is currently tied to a floating marker while I get the code and physics constants set. Example:

Guys are you still trying to figure this put? There has been no update for quite a while now...

[porroone]

Well I figured out that what I was trying to do was very complex, so i'm starting from something easier, like adding new animations to behavior and such, its a looong learning curve.

[Keldis]

If there would only be a way to detect collisions, then this whole process would be much more easy to do.

 

Then we could work with the translate to command and would not have to fight with behaviors, which in some cases dont look for collision either.
