This function sets an entity's pick mode.

Syntax

• void SetPickMode(const int mode, const bool recursive=false)

Parameters

• mode: The entity pick mode to set. This can be any of the following values:
  • 0: pick tests will skip this entity.
  • Entity::SpherePick: a sphere test with the entity pick radius will be used.
  • Entity::PolygonPick: if the entity is a model or a brush, a precise polygonal pick test will be performed.
  • Entity::BoxPick: a box test with the entity pick radius will be used.
• recursive: if set to true, the specified pick mode will be recursively applied to the entity's children.

Example

#include "Leadwerks.h"

using namespace Leadwerks;
int main(int argc, const char *argv[])
{
        Leadwerks::Window* window = Leadwerks::Window::Create();
        Context* context = Context::Create(window);

        Camera* camera = Camera::Create();
        camera->Move(0, 0, -8);
        Light* light = DirectionalLight::Create();
        light->SetRotation(35, 35, 0);

        //Create a model
        Model* model1 = Model::Box();
        model1->SetPosition(2, 0, 0);

        Model* model2 = Model::Box();
        model2->SetPosition(-2, 0, 0);
        model2->SetPickMode(0);// Disable picking on the first hit entity

                                                   //Create a sphere to indicate where the pick hits
        Model* picksphere = Model::Sphere();
        picksphere->SetColor(1.0, 0.0, 0.0);
        picksphere->SetPickMode(0);
