                        if (crimeCar != null)
                        {
                            Game.LogTrivial("######### Signal before collision check ############\");.");

                            if (NativeFunction.Natives.HasEntityCollidedWithAnything(crimeCar))
                            {
                                Game.LogTrivial("######### Signal from collision monitor ############\");.");
                                crimeCar.EngineHealth = crimeCar.EngineHealth - 50;
                                Game.DisplaySubtitle("~r~purp-Car damaged is: " + crimeCar.EngineHealth, 5000);
                            }
                        }

Above is a snippet that i expected to be functional, but it crashes my plugin, with :
Exception message: Cannot convert null to 'bool' because it is a non-nullable value type

But that makes no sense.
The check in HasEntityCollidedWithAnything(crimeCar) is secured in the entrance of the segment:
if (crimeCar != null)
HasEntityCollidedWithAnything(null) is not possible(?)
If crimeCar was null, then the expression should never be executed.
The api says that HasEntityCollidedWithAnything() returns a bool:

Spoiler

HAS_ENTITY_COLLIDED_WITH_ANYTHING
bool HasEntityCollidedWithAnything(int /* Entity */ entity);

Called on tick. Tested with vehicles, returns true whenever the vehicle is touching any entity. Note: for vehicles, the wheels can touch the ground and it will still return false, but if the body of the vehicle touches the ground, it will return true.

Namespace: ENTITY

What am i missing?

The problem is that the dynamic call resolution is missing the return value hint, so it does not know what to return. You need to use the generic parameter to hint, such as HasEntityCollidedWithAnything<bool>(..). All functions invoked via the Natives class are dynamically resolved and there is zero type information available unless explicitly provided by you.

Thanks once again!
