Hello,
I'm new to Game Editor and trying to make my first game, based on golf. I can set a golf club with speed and angle to get a ball hit up into the air by the player, but the bounce using collision doesn't look natural and it doesn't stop. Any tips would be appreciated.

To make it look really accurate, you will have to calculate the velocity of the ball, given angle and speed. Then on collision set the velocities of the ball. Generally you can use angle and directional_velocity, but depending on your calculations, or lack thereof, there will be varying levels of accuracy.

Ball>draw Actor>

Code: Select all

directional_velocity *=.98;   //make ball slow down
if(directional_velocity<.01){  //make ball stop if nearly stopped (prevents shaking)
directional_velocity=0;
}


You can also then create a float (real) array, and set the slowdown for terrain types;
for instance

Code: Select all

tslowdown[0]=.998;  //speed to slow down while in air
tslowdown[1]=.99;    //speed to slow down while on grass
tslowdown[2]=.90;    //speed to slow down while on sand

then have the ball start with a terrain of 0; and change that to 1 on collision with ground, or 2 on collision with sand trap.

then

Code: Select all

directional_velocity*=tslowdown[terrain];

You could just nix the slowdown in the air, that may be best if it doesn't slow down till it hits something.

Then on your collision, try adjusting the power of the ball. There are 4 variables in physical response;
The 3rd one is 'final velocity multiplier' for event actor. You can adjust this till you get a response you like.

Thanks - I will try that straight away
