Testing to see if a collision would occur if you moved a object

by Philip Loyer · in Torque X 2D · 03/20/2008 (6:45 pm) · 5 replies

Hi Guys and Gals, I am trying to figure out a way to test to see if I moved my T2DSceneObject to a specified place to see if a collision would occur there and if it would to not move it. One problem I have is it could be any sort of random objects that it could bump into. Any ideas would be greatly appreciated. thanks!

Ever get that feeling when you get so close to the answer you've been looking for, however it eludes your grasp? Well thats where I am now.

I have found this which I think will work for my purposes.

GarageGames.Torque.T2D.T2DSceneGraph.Instance.FindObjects()

Which does a radial search. The problem you might ask? Well for some reason unbenownst to me is for some reason my T2DSceneGraph object reference does not have a Instance property. Could someone please shed some light on this subject? It's starting to drive me more bonkers than I already am.

Thanks a ton!

In Torque X 2.0, multiple scene graphs are now supported so there is no longer a T2DSceneGraph.Instance. Instead, you can start with your T2DSceneObject and access its scenegraph through its SceneGraph property. From there you can call FindObjects.

Could I get a code example? I still seem to be have some trouble here, I cannot find the FindObjects method at the root of the SceneGraph property. Any Suggestions?

Thanks for the help. Phil

Sorry, I missed a detail ... you need to go through Container as well. Here's an example:

T2DSceneObject myObject = TorqueObjectDatabase.Instance.FindObject<T2DSceneObject>("MyObject");
myObject.SceneGraph.Container.FindObjects etc.
