Can someone write an Expression for a drone?

[ryan1271]

I only know the very basics about Expression 2 but I want a drone that orbits me and can attack people.

I want it to be chat controlled:
"-orbit" makes it start orbiting me
"-stoporbit" makes it stop orbiting
"-ram" makes it fly at the person I'm looking at and kill them
"-stopram" makes it stop ramming the person

And I want the expression model to be the small PHX sphere. I am probably asking for too much but I would appreciate it if someone made one for me.

We don't hand out codes.

Try to make it yourself, and then we'll try and help you out when you encounter problems.

I would make an attempt if I knew anything about Expression 2 but I don't and I wouldn't fell right about stealing someones code.

I just figured it wouldn't hurt to ask.

Read tutorials, I got one in my sig.

Learn expression 2. It's pretty easy.

Ok Spectre, I read your whole tutorial and it seems simple enough. I have a few questions though. Am I using a hologram for the drone? And if I am does that rule out the ram feature because holograms are nocolided with everything? And if I want the drone to orbit me does that mean I have to use trigonomety to change the vectors?

[SpectreCat]

You can use a hologram if you like, or use apply force

If you do use a hologram, it will be noclided with everything, so you cannot ram.
(For a drone, I would use apply force)

To make something orbit, you do need trig. But I gave you how to do it in the tutorial.

Ok, I used your code from the tutorial but that only makes it rotate, not orbit. I tried to modify it to work but it only goes in a line over my head.

I don't know any trigonometry but I think I need sin and cos right? Help

You don't necessarily need trig, it can be done by rotating vectors too.. but yes, sine and cosine are what you would need if you went the trig route.

Using vectors, you could do something like:
I++
Position + Direction:rotate(ang(0,I,0)) * Distance

Which would rotate your direction vector around the Z axis as I is incremented. Distance is essentially the radius.
