C++ Question Why am I getting these spotlight errors?

[tauruslittrow84]

When I use this code

docking_light = (SpotLight*)AddSpotLight(_V(0.0,-1.022404,12.6), _V(0,0,1), 150, 1e-3, 0, 1e-3, RAD*25, RAD*60, col_white, col_white, col_a);
docking_light->Activate(true);

I get all these errors when trying to create a spotlight module. What have I forgotten in my header?

I get all these errors when trying to create a spotlight module. What have I forgotten in my header?

Looks like cargo-cult programming TBH. Sorry to say that, but it seems you are trying to code by means of putting snippets together without really knowing what's going on. If that is so, please keep in mind that - going forward - everything you assume to be the error could very probably be totally wrong.

First of all: your problem seems to be unrelated to spotlights at all. Second, why do you include both OrbiterAPI.h and OrbiterSDK.h? Third, if that is your entire code, where is the header file?

I can only guess here, but it looks like you never declared docking_light as a field. Same with col_white and col_a, which you also never initialized.

Not sure if you are adding spotlights to a vessel or compiling the spotlight vessel. For me it is just easier to add an attachment point and then attach a spotlight vessel. But you have to switch to it and turn on,.....

But if adding spotlights to your vessel then I don't think you need:

#include "spotlamp.h"
