When I try spawning a second mig, it crashes, even with new variables for world and create_instance. Also is there a way to make it spawn an object as a static model instead of a vehicle?

Must be a bug in last build, because it works normally here.
Static object - just give it the object path. The last argument is permanent - true if the object should be made permanent in the world, applies to static ones.

What's the format for xyz co-ordinates for #pos or #rot?

tried w.create_instance("outerra/mig29/mig29", #(pos 10, 20, 50), #rot, false) and variations thereof to no avail.

#pos or #(pos distance) are macros that expand to the current world position + distance ahead. Normally you'd write a position vector there, like {x:6000000, y:14124, z:-1135222}. It's in ECEF.
#rot is rotation quaternion of the camera. Entering quaternion manually is the same (it has also w: component), but you'll probably rather want to convert it from Euler angles. Unfortunately there's no vector math library included in javascript, so working with vector operations is clumsy.

Ctrl+F4 : Recorder

What does it record? Is it recording video in another format? I tried to record something with it but when i hit record, the window close and i see the red dot with the time but i can't reopen that window with ctrl+F4 so i cant stop recording whatever it records.

I think that was used to record vehicles and aircraft and their flight paths, to be replayed later. But it was just a temporary stuff, it should not be accessible there.

Can any of these commands be executed from within a vehicle's JS file? I'd like to be able to spawn smaller objects from larger ones.

You could query the world interface and call the equivalent methods, but it's not guaranteed to stay supported. We should add methods to spawn objects from within other objects. I guess initially they should be attached to the parent, and then released while inheriting the motion vectors etc.

You could query the world interface and call the equivalent methods,

Could you give an example of that code? Thanks.

And I guess another future request is an option to stop vehicles from automatically resetting to ground level when they're spawned.

[cameni]

Code: [Select]

var world = this.$query_interface("ot::js::world.get");
var vehicle = world.create_instance("outerra/ddg/ddg", pos, {x:0, y:0, z:0, w:1}, false);

This does not reset vehicles to ground, that's just what the object placer does.

Sorry to bother you again but how would I execute $con.get_hpr() from a js file?

[cameni]

From what js file? A vehicle script? Vehicles have this.heading_pitch_roll() function.

[zzz]

I'm sorry, I meant "get_camera_angles()", though that heading_pitch_roll function is indeed a useful unlisted command.

and, yes from a vehicle script.

[cameni]

get_camera_angles() returns lat/lon of current camera position. If you want to get lat/lon of a point, you could use the following (returns radians):

Code: [Select]

lon = Math.atan2(p.y, p.x);
lat = Math.atan2(p.z, Math.sqrt(p.x*p.x + p.y*p.y);

If you specifically want the coordinates of the camera, I can't think of a way to get them from vehicle script ... but if you want the angles for the object, you can use the code above with its position.

I was hoping it had the angles set_camera_angle had but thanks anyway.
