Hi!

right now i am working on a tank, and i got 2 questions:

my first question: how do i make my turret on the tank, not to collide with the tank? because my tank can't move, when i put the turret close to the tankbody, but if i take it away from the tankbody, then my tank, can move again.

my second question: when i move my tank up a mountain or something else, then it moves like this:

how do i make it move up like this?:

Lool in the Menue: "Proberties" in WED by your Model.

To your first question: Have you tried making the turret passable? set(my, PASSABLE). An alternative is to set both their "group" variables to the same nonzero number. Look up "group" in the manual. You'll need to use "IGNORE_PUSH" in your collision functions.

To your second question:

Hopefully you find that helpful

can you please write an example for the first question, i can't make it work with the group thing?

thanks!

okay i solved my first problem, thank you very much for the help!
now i will try solve my second problem.

thanks!

Do a trace downwards from the tank, and set it's rotation to the target rotation using vec_to_angle.
If you need any help on that, let me know, i can whip up a piece of code for you

regards,

that would be great if you could write me an example for that! thank you!

second question answer: Courtesy of George's answer to a question in AUM 36, slightly modified to work in Lite-C.

action tank()
{
ANGLE temp;

while(1)
{
temp.tilt = 0;
temp.roll = 0;
temp.pan = -my.pan;
vec_rotate(normal, temp);
temp.tilt = -asinv(normal.x);
temp.roll = -asinv(normal.y);
my.tilt += 0.1 * ang(temp.tilt - my.tilt); // play with 0.1
my.roll += 0.1 * ang(temp.roll - my.roll); // play with 0.1
wait(1);
}
}

OK, thank you it works!, but know i got 2 other questions:

when i stop in the middle of the "mountain", then the tank returns to its old "way" like in picture 1. how do i solve this problem?

and how do i make the tank's turret and cannon to act the same way as the tankbody?

thanks!

Could you post your tank movement code, that helps us in solving the rotation issues

tanks,
