Unhandled exception thrown while creating a colldier in Component:Start

[Dreikblack]

For example in ThirdPersonControls

	virtual void Start()
	{
		smoothcameradistance = followdistance;
		auto entity = GetEntity();
		entity->SetPhysicsMode(PHYSICS_PLAYER);
		if (entity->GetMass() == 0.0f) entity->SetMass(78);
		entity->SetCollisionType(COLLISION_PLAYER);
		//here
		auto collider = CreateMeshCollider(entity->As<Model>());
		if (collider) entity->SetCollider(collider);

		camera = CreateCamera(entity->GetWorld());
		camera->SetPosition(0, eyeheight, 0);
		camera->SetRotation(0, 0, 0);
		camera->SetFov(70);
		currentcameraposition = camera->GetPosition(true);
		freelookrotation = entity->GetRotation(true);
	}

Are you certain that entity->As<Model>() isn't returning NULL?

Why are you setting a collider? The player physics mode will create several cylinder shapes to handle the collision.

Yes, i did check in my own component, just simplified it here.

It's just an example for model that start map has. I don't use ThirdPersonControls or player physics mode in my project. Just wanted to apply a collision in Start om my units component. Have no problem with doing that outside of component while taking entities from world.

The problem has to do with instantiating an animated model. Still investigating...

[Josh]

This works fine:

#include "UltraEngine.h"

using namespace UltraEngine;

int main(int argc, const char* argv[])
{
    auto world = CreateWorld();
    auto model = LoadModel(world, "Models/Developer/Player/player.mdl");
    auto inst = model->Instantiate(world);
    return 0;
}

I see what was happening.

The mesh collider routine creates an instance of the model and collapses it, then uses that mesh data to build the shape. But it was using the default parameters for instantiation, which includes running the start function for any attached components on the new model. So it was creating an infinite recursive loop.
