Fix object in the terrain, what's wrong??

[angel80]

Hi everybody,

I have set up an function to set all my objects load in the irrlicht engine in the ground

Code: Select all

void ECSS_StaticObject::fixGround(void)
{
	
	f32 middleObject = (objectMeshNode->getTransformedBoundingBox().MaxEdge.Y) - (objectMeshNode->getTransformedBoundingBox().getCenter().Y);
	vector3df start = objectMeshNode->getPosition();
	vector3df end = start;
	cout << "Start  " << start.Y  << endl;
	end.Y=end.Y- 20000.0;
	cout << "End  " << end.Y  << endl;
	triangle3df triangle;
	line3d<f32> line(start, end);
	device->getSceneManager()->getSceneCollisionManager()->getCollisionPoint(line, terrainSelector, end, triangle);
	cout << "Collision at   " << end.Y << endl;
	f32 distance = (start.Y-end.Y);
	
	start.Y = start.Y - distance;
	cout << "Distance height" << start.Y << endl;
	objectMeshNode->setPosition(start);
	objectMeshNode->setDebugDataVisible(true); 
}

some object are well fixed but some other not. What's wrong in my code.
It's just doing a collision bettwen the object and the ground and set the position to the meshNode.
Is it becase setPosition is setting the relative position??? how to do because there aren't setAbsolutePosition function

Thank for help!!

Judging from your remark, apparently you set every object's position relative to the ground, whether or not it is attached to a parent object.

Question is: why? A child object (whether that is a gun in a player's hand, a turret on a tank, or whatever) is something you normally want to place relative to the parent object.

Hi Guest,
I fixed all objects to the ground and everything is ok now. Thank a lot

Hi angel80,could you post your working code about the problem you had mentioned in this thread?
Thanks!!!
