How to apply force to a body?

[x1911]

for example, i want a ball move to right side,

and i have tried to use body.applyImpulse ({
x:0, y:0, z:100
}, 10);

unfortunately it dosen't work.

BTW: how to make a ball jump in this case?

Forces are directional, hence your force should be a vector3 too.

Oimo.js/src/core/RigidBody.js

Line 425 in 159ef4e

applyImpulse: function(position, force){

@w84miracle thanks for reply, have you some example to show how this works?

has other way to apply force except body.applyImpulse ?
if i want to keep the gravity [0, 9.8 ,0]

no look code in
http://lo-th.github.io/Oimo.js/#planet
you can keep gravity ;)

maybe your impulse is no strong enouth to jump
i try a example soon

force in oimo needs to be updated in every frame. no update will not see the effect.
body.applyImpulse ({x:0, y:0, z:0}, {x:0, y:20, z:0});
