Ok it seems im too stupid to understand vectors in 3DGS or maybe they make it so hard that only a few can understand them.
I hope someone can help me with some vectors scripts,because right now im starting to regret that i spend all this money on this program
So, this is what im trying to do:
i have a platform with 9 holes in it from which 9 models appear
i have a hammer above camera so is not visible all the time but it have the same x, y coord as the camera and the z+50
when a model appear from a hole and i click it with the mouse i want my hammer to move from his position to model position on a circle arc and hit that model
and here my problems start:i cant make that hammer to move on a circle arc in 3D space :(((.Ive read the manual, online tutorials but all are only for 2D moves and i cant adapt to 3D moves
PLS help :))
thx

Is this that what you want?

hammer.x+=(circle.x-hammer.x)*time_step;
hammer.y+=(circle.y-hammer.y)*time_step;

basicaly what i want to do is to move a model from A(x1,y1,z1) to B(x2,y2,z2) on a circle arc in 3D space
Thx for your replay, ill try to include that to my script and include the z coord too :), i hope it will work

Its more a math problem, than some functionality that should
be provided by the engine.

A simple sollution to your problem would be to make te hammer-model,
extend the origin-point of the model some way off the shaft,
and then simply lett the hammer model tilt down 90 degrees.

So you only ROTATE the hammer-model.

This way the hammer would move on a quarter circle path, just like
slamming a hammer on a forge.

any chance of uploading an image of what you're after with which parts you need to rotate, or ideally a video of it working in another game?

you could rotate it, and at the same time make it go forward RELATIVE to the angle. this should work.

MrGuest here is the picture u want. I hope u cen see the link its my first time when i upload something :)))

Anyway here is the code ive done so far but is not working

entity* MainObject;
var distance;
var tempo;
var temp_dist;
var angle1;
var angle2 = 90;
string target_mdl = "hammer.mdl";
bmap mouse_pointerr = <cursred.bmp>;



action CameraPoint
{
MainObject = me;
my.invisible = on;
my.passable = on;

}

function Camera_Init()
{
wait(10);
while(1)
{
camera.z = MainObject.z + 10;
camera.x = MainObject.x;
camera.y = MainObject.y;
camera.pan = MainObject.pan;
camera.tilt = MainObject.tilt;
camera.roll = MainObject.roll;
wait(1);
}
}

function adjust_target()
{
vec_diff (temp,nullvector,target);
vec_to_angle (my.pan,temp);
}

function create_target()
{
var pos1;
var pos2;
pos1.x = mouse_pos.x;
pos1.y = mouse_pos.y;
pos1.z = 5;
vec_for_screen (pos1,camera);
pos2.x = mouse_pos.x;
pos2.y = mouse_pos.y;
pos2.z = 20000;
vec_for_screen (pos2,camera);
c_trace (pos1,pos2,IGNORE_PASSABLE);
distance = vec_length(target);
tempo.x = 0;
tempo.y = 0;
tempo.z = distance;
tempo.tilt = 0;
tempo.roll = 0;
ent_create (target_mdl,tempo,adjust_target);
wait(1);
angle1 = vec_to_angle (my.pan,temp);
vec_set(temp,nullvector);
while (angle2 > 0 )
{
temp_dist = cos(angle2)*distance;
temp.x = cos(angle1)*temp_dist;
temp.y = sin(angle1)*temp_dist;
temp.z = sin(angle2)*distance;
angle2 -=2*time;
c_move (target_mdl,temp,nullvector,IGNORE_PASSABLE);
wait(1);
}
}



function mouse_startup()
{
on_mouse_left = create_target;
mouse_mode = 2;
mouse_map = mouse_pointerr;
while(1)
{
vec_set (mouse_pos,mouse_cursor);
wait(1);
}
}


Well not all the code lines belong to me ,:)) some of them i copy/paste from others

Hi!


If the action around the 9 holes is always the same you could
make a path in WED ...place a node at every hole and then
slide from one node to the other when you click on the mouse.

I discovered how to move an object in 3D .Long live Google
By using matrix and quaternion, still too complicated for me so ill stick with 2D movement,its a lot easy and not soo complicated to program with C-Script
Thx for your replay

to move an object in gs is easier than in other systems.
as i remember right, in opengl you have to draw your world again with new coordiantes of the object. in gamestudio the engine do it. you just have to call c_move or change the corrdiantes.
a translation-matrix isnt so complicated
1 0 0 x
0 1 0 y
0 0 1 z
0 0 0 1
just multiply it with the current world-matrix
more complicated are rotaions :p
