simple moving a char (again sorry)

hello ive been surfing this forum and i found some ideeas of movin a char
but i cant seem to put togheter a workin code..
i have a working simple gravity callback but i cant make a simple moving one: the reason HOW can i Calculate the direction/moving vector so i can add it to the body...
so my request is if there is someone who can show/give nice example of a movin calback that will drag the caracter and make him move forward whatever its orientation...

10xz in advance

You need to move the body using forces. For example:

// move forward

if (mInputDevice->isKeyDown(KC_UP))
{
Vector3 direction = ash->get_node()->getOrientation( ) * Vector3::UNIT_Z;
ash->get_body()->setVelocity(ash->get_body()->getVelocity()*Vector3(0,1,0) + direction*(10)*Vector3(1,0,1)*size_factor);

}


Try it

thankz @Hansel ill try it a bit later when ill start working... lets hope thats gonna work [-o<

One question what is SIZE_FACTOR>??<

Forget size_factor, it`s a parameter to adjust the velocity of Ash according to his size

ok i tryed your code.. its awsome 10xz but its going backwards so i replaced UNIT_Z with NEGATIVE_UNIT_Z and is goin normal .

well... almo0st normal when it hits the ground (anyway it bounces ) and it starts rotating seting up friction 0 and elasticity 0 with OgreNewt Materials will do the trick?

if you have done that allready i could use some help

10xz


const MaterialID* material_ash = new MaterialID( world);
const MaterialID* material_floor = new MaterialID( world );


MaterialPair* material_pair = new OgreNewt::MaterialPair( world, material_ash, material_floor );


material_pair->setDefaultFriction( 0, 0 );
material_pair->setDefaultSoftness(1);
material_pair->setDefaultElasticity(0.1);
material_pair->setContinuousCollisionMode(0);


ash->get_body()->setMaterialGroupID(material_ash);
floor->get_body()->setMaterialGroupID(material_floor);

man u are a true helper 10xz a lot.. Ill trry that in the mornin cuz here its 22:55 pm what can i say more thankz a lot. i think there are about 4 of us that surf this forum daily

man thanks a lot you saved me from 2 hours of searching throughout the forum and tutorials. If you need anything related to ogre or ogrenewt just ask becoz i have a huge prject with lots of things in it

What's you project? I have curiosity

im makin a rpg/mmorpg game and its infrastructure its done after 6 months of work. And now we just have to make the models and programm the interaction with the enviroment
and now im workin on the AI

It sounds very complex, how many people are working with you? Do you have any artwork or screen?

Hope you'll finish it well

there are 3 of us and the release date is in september .. i dont know if im allowed to post the site but i hope no one will be mad on me

http://www.lhok.as.ro
there you can see some screenshots and later when we will implement other models in the game and the AI ill post new screens

I've probed the alpha version and the gui implementation looks very impressive. I like your work

Are those trees modelled in max?

yes they are exported from max.. Its from the base vedetaion from max but later on well model one of our own.. and i found on some sites vegetation packs ... with tropical trees and ... eh.. very impresive..
Glad you like it ill hope to hear your opinion on the release
Btw which country are you from???

I'm from Spain, and you?


edit.- Bucharest?

yeah, Romania keep up the good work.. and im on the way of implementing the AI.. its not that hard after i read some articles.. if u have probs related to this subject or other please feel free to ask ill help as much as i can
