wow

Not sure what you are doing, but I simplified some of your code in case it helps:

in postStep:
a := app.mousepos(0);
keys.isdown("w") ? {
_player_pos = _player_pos + [math.cos(a), math.sin(a)] / 10.0
} : {};
keys.isdown("s") ? {
_player_pos = _player_pos - [math.cos(a), math.sin(a)] / 10.0
} : {};
keys.isdown("d") ? {
_player_pos = _player_pos + [-1.0 * math.sin(a), math.cos(a)] / 10.0
} : {};
keys.isdown("a") ? {
_player_pos = _player_pos - [-1.0 * math.sin(a), math.cos(a)] / 10.0
} : {}

in update:
sim.running ? {
a := app.mousepos(0);
for(String.length(_circle), (i)=>{
_relative = math.atan2(_circle(i) - _player_pos(1), _circleZ(i) - _player_pos(0));
_distance = math.vec.dist([_circle(i), _circleZ(i)], _player_pos);
_distance < 5 ? {
_player_pos = _player_pos - [math.cos(_relative), math.sin(_relative)] / 5.0
} : {};
_distance < 75 ? {
Scene.addPen({
pos := [scene.my.view(0) + (_relative - a) * 8.0 / math.pi, scene.my.view(1)];
followGeometry := true;
size := 10 / _distance;
color := [0, 0, 0, 1.0];
timeToLive := 0.034;
Zdepth := 7.0
})
} : {};
})
} : {}

oh, wow, thanks! oh, a and d doesn't work in your code, I'll fix it.

I was trying to make something where you can look up but then the distance variable was BAD. Do you know a distance equation for 3 axis?

ezpz, it's just two pythagoreans on top of one another, first find the horizontal distance (2d distance), then put that and the vertical distance into pythagoras.

thanks.

I don't understand why you say "a and d doesn't work in your code". The code is mathematically equivalent. I can copy and paste it into postStep and it functions exactly the same. Maybe somebody else can try it out.

For now I'm just using the old code but when I press a and d it is equivalent to w and s. I don't know, maybe I'm making a mistake. I'm not very good at maths.

No, it's my mistake. I forgot to multiply some terms by -1.0. My apologies. The code has been corrected above.
