[Tutorial] How to Interact with objects through the wall

[darkwiings]

Hello!


I know a lot of people that prefer that items can be picked up through the wall. Me for example haha.


Well, let's go. It's super simple.

In AI_Player.cpp search for:

            if(distance > d)            {
                // check dist to player
                if((objCenter - GetPosition()).LengthSq() > (maxDist*maxDist))
                    continue;
                // check if both player and camera are facing object
                if((GetPosition()-objCenter).Dot(gCam-objCenter) < 0.0f) 
                    continue;
                // check ray cast that you can see that item
                bool isVisible = false;
                r3dVector objSizeBBox = obj->GetBBoxWorld().Size/4;
                r3dVector posToTest[5] = {objCenter,objCenter+r3dVector(-objSizeBBox.x,    objSizeBBox.y, -objSizeBBox.z),
                                                    objCenter+r3dVector( objSizeBBox.x,    objSizeBBox.y, -objSizeBBox.z),
                                                    objCenter+r3dVector(-objSizeBBox.x,    objSizeBBox.y,  objSizeBBox.z),
                                                    objCenter+r3dVector( objSizeBBox.x,    objSizeBBox.y,  objSizeBBox.z) };

Replace the red text for

bool isVisible = true;

Compile and be happy!

If i help you, rep+

Sorry bad english.
