how this crane system look like and how should it work?

If I can to get done with this system I will post a video here.
You can be a crane driver, your job is to take containers with that and put it on ship, that's the idea

Maybe

(Ropeheight + Magnet height) = Magnet actual height
I've made a pilot cargo job and calculated the height like this and it's work fine.

You didn't read what the problem was at all. Anyways I need to come on your server and show me what the problem is maybe we can do a team viewer session and I will help you figure it out.

I know how to get height, but i need real X and Y pozition on the map.

Answer at my PM, please.

Could you give us your createobject lines, to lazy to look up the modelids

And the _lnx part is kind of unnecessary

Because you can get the offsets with Streamer_GetFloatData if I am not mistaken

Also I am wondering, isn't is just the z rotation of your crane + distance of magnet +- height?, provided the crane is on a flat surface.

Something like that?

pawn Код:

x = craze_base_x + distance_to_magnet * floatsin(-crane_z_rot, degrees);
y = craze_base_y + distance_to_magnet * floatcos(-crane_z_rot, degrees);
z = craze_arm_z - magnet_offset;

Re: Need help with spatial geometry - Pottus - 12.02.2019

But Nero he needs the rotation of the magnet since it is attached to objects the real world rotation of that magnet needs to be calculated through the attached object hierarchy object by object. If he attaches an object to the magnet then it wouldn't look smooth and just snap to an arbitrary attach rotation.

Bump
I will try your sugestion Nero, thank you.

Well if the magnet is attached to the crane it should rotate with the crane, staying in its relative position.

To attach something to the magnet we would need the correct z offset, probably depending on the size of the target and the difference in z rotation
x, y offset depending where the magnet attaches the target, x, y rotation shouldn't matter

Anyway that is what I am thinking, to verfiy that I would need to test it

if you got your x and y of your magnet (#27) and x and y of your target you calculate the difference and use it as offset

how the attachment process gets triggered is up to you, maybe Objects Physics

another sugestion?
