Hi.
One area I'm kind of stuck on right now is making the characters in my =
game (a 3rd person style game) interact
with the physics environment in a correct manor. I use a simple box to =
represent them at the moment.
The main problems are:
1. The character should always be standing vertically, whereas naturally =
any physical collisions tend to
make the box wobble on all axis'. I'm fixing this by just manually =
setting the rotation each frame but it
doesn't feel like a very good way to do it.
There will be certain circumstances where I want to allow free =
rotation's (player has been killed, or is
flying off after a nearby explosion etc.)
2. I need a mix of "direct control" and physics response from ODE.
For example, I want perfect control over the orientation and velocity of =
the player according to the player
input (including things like instantly stopping when the player stops =
pressing forwards). But if for example,
he walks over 'see-saw' or a falling object strikes him then its the =
physics that has more baring on his resultant
position. I guess if I can solve No.1 in more friendly way, this be =
easier.
I hope my general problem has got across adequately.
I'm looking for any pointers or ideas for what I should try out next.
Any help greatly appreciated!
Thanks
igrok.
