[SOLVED] getIntersection() with dynamically created mesh

[dark99]

World::getIntersection with dynamically created mesh dose not work

test code is here

--------------------------------

        auto mesh = ObjectMeshDynamic::create();
        mesh->allocateVertex(4);
        mesh->allocateIndices(6);
        mesh->addVertex(vec3(0, 0, 1));
        mesh->addVertex(vec3(1, 0, 1));
        mesh->addVertex(vec3(1, 1, 1));
        mesh->addVertex(vec3(0, 1, 1));
        mesh->addIndex(0);
        mesh->addIndex(1);
        mesh->addIndex(2);
        mesh->addIndex(0);
        mesh->addIndex(2);
        mesh->addIndex(3);
        mesh->addSurface("mat0");
        mesh->setIntersection(true, 0);
        mesh->setIntersectionMask(1, 0);
        mesh->updateTangents();
        mesh->updateBounds();

        
        auto obj = World::getIntersection(vec3(0.5, 0.5, 2), vec3(0.5, 0.5, 0), 1);
        if (obj)
        {
            Log::message("hit\n");
        }

Could you please specify SDK version that you are currently using?

Thanks!

Hello! 

have you tried to call World::updateSpatial after node creation? 

As a new node becomes a part of the BSP tree only after the updateSpatial()method is called (the engine calls the method automatically each frame after the world script update()code is executed), all engine subsystems can process this node only in the next frame.

It works after call World::updateSpatial()

Thanks !
