I am trying to make a Mini Golf Game with the Newton Wrapper. I looked at the tutorials and even searched the forum for help. I got some help and solved most of my problems but i really need help on this question and i cant find it when i search the forum.
my question is when i put velocity on the golf ball and i hit it. It moves and hits a wall and bounces off like it should. Well it keeps on moving after it it the wall I add the friction but the ball keeps on moving. here is the code for that
sync on
sync rate 30
hide mouse
ndb_newtoncreate
`-------
`gravity
`-------
NDB_SetVector 0.0,-100, 0.0
NDB_SetStandardGravity
world = NDB_NewtonMaterialGetDefaultGroupID()
ball=NDB_NewtonMaterialCreateGroupID()
NDB_NewtonMaterialSetDefaultFriction world,ball,1, 1
Anyway it doen't work if slows done but the ball still keeps on moving. it never completely stops moving
Can anyone help me with this problem. Thanks in advance and here is the rest of the coding from my game so far so you guys can look through it and see whats wrong. if there is nothing wrong tell me what i can add to it to get what i am looking for.
