Another thread another problem.
From yesterday I can not use properly the function SC_GetCollisionSlideX (SC_GetCollisionSlideY and SC_GetCollisionSlideZ). The program freezes when it should go to place the object that collided.
The problem resides in the fact that SC_GetCollisionSlideX (SC_GetCollisionSlideY and SC_GetCollisionSlideZ) return a value of 1.#QNAN00. In the last day it worked, but since yesterday no longer works, and I do not seem to have changed anything. Is also very strange that if I use one object the function works, if I use two or more objects there is the problem. Moreover, if I use in the setup as the type of collision Collision box (2) two objects of the same type do not create problems, while 3 and more yes. When used as a kind of collision the Sphere collision (1) the problem is not created with an object, but with two or more objects.
In the image you can see that SC_SphereSlide return 1 (the terrain) but SC_GetCollisionSlideX return 1.#QNAN00.
Here some code.

SC_SetupObject( i+firstEnemies, groupEnemy, 1 );
The function that move enemies (objects that collide with ground and which create the problem.

Have you have any solution?
