As I said in the subject, I have some problems in managing with collisions with the Sparky's ibrary.
Following the examples provided with the library I wrote a small application, but, unfortunately, I have two problems.
The first problem is that I can not handle properly the collision of an object, in fact, that, instead of following the terrain, flying through the map (as if he had not gravity). On the ground, however, do not collide, so collision run successfully.

Variables


This is the initialization of the terrain


This is the initialization of the object


This is the function that control the movement of the object (collisions and gravity)



The second problem, however, relates to another object falling through the ground, so the collision is not done correctly.

This is the function that control the movement of the second object (character played by by human)


Have you have any idea?
I simply took the source code of examples and adapted it to my little scenario.
In attachment I uploaded binaries of the two cases.

Thanks in advance for you replys (and sorry my bad english).

I didn't try your code or read too carefully, but I think this line could cause trouble when working with terrains:



If I remember correctly there is a terrain specific setup command in Sparky's Collision. Something like this:



But you would have to look into the documentation for that.

From what I read SC_SetupTerrainObject has been deprecated and instead SC_SetupComplexObject is used for the setup of terrain . This is also confirmed by the compiler; indeed if I try to put SC_SetupTerrainObject it tells me to replace it with other.
However, I have made ​​some progress, and the movement of the object controlled by the user (gravity and collisions work). I think that the problem was caused by initialization of the initial position of the object, which was a unit under the terrain level and so do not collide on the ground.
Unfortunately I have the same problem with the other object that continues to fly through the map and pass through the ground.

I solved the previus problem in this way:

It's not the right ways (I wanted to use the cast collision), but for now it's okay.

I have another problem: I want to shoot bullets depending on where you point the mouse cursor, I implemented this solution but bullets does not move.
Any idea?


Thanks in advance for your answers.

EDI 1:
Some updates,
now the bullets move, but the collision with terrain sometimes it is not accurate and sometimes not collide.
I think that the problem it is the Z component of mouse cursor.
