Welcome. I tried to get objects colliding with each other in new component system, but no way.
I obviously used and I am trying to catch collision event like this:
So I managed to get this work. The only bad thing is I can't get collider !
In previous system in IGameObjectExtension there was HandleEvent method that had SGameObjectEvent parameter, and this parameter had pointer to the collider. Current ProcessEvent has only SEntityEvent parameter, which does not have any sort of pointer. How Do I get collider then? I tries nParam to see if any of 4 slots of this array returns maybe entityId, but nope.

Figured out! If anyone is looking for solution there it is.. Getting collision in ProcessEvent method:

Code: Select all

void ProcessEvent(SEntityEvent& event) override { switch (event.event) { case ENTITY_EVENT_COLLISION: { EventPhysCollision *physCollision = reinterpret_cast<EventPhysCollision *>(event.nParam[0]); if (physCollision) { IPhysicalEntity *pThisEntityPhysics = physCollision->pEntity[0]; IEntity *pThisEntity= gEnv->pEntitySystem->GetEntityFromPhysics(pColliderPhys); IPhysicalEntity *pColliderPhysics= physCollision->pEntity[1]; IEntity *pCollider = gEnv->pEntitySystem->GetEntityFromPhysics(pThisPhys); //Now just check if the collider entity is valid if(pCollider) { //Do something to your collider } } } break; } }

You tested this method? I tested , it is wrong! May be I am wrong cause I get a nulptr value of pCollider, but it is here a new method? Or that is true?

It could be that the IPhysicalEntity was not part of an Entity, so GetEntityFromPhysics would return a nullptr. It looks like there's also a tiny mistake in the code snippet, because it is using pColliderPhys for pThisEntity and pThisPhys for pCollider. This is how I think it was intended to be used:
Also keep in mind that this event has two parameters: You can also have a look at this code to see how we use this event to gather all the collision information to send it to C#.

if (physCollision)
{
IPhysicalEntity *pThisEntityPhysics = physCollision->pEntity[0];
IEntity *pThisEntity = gEnv->pEntitySystem->GetEntityFromPhysics(pThisEntityPhysics);
IPhysicalEntity *pColliderPhysics= physCollision->pEntity[1];
IEntity *pCollider = gEnv->pEntitySystem->GetEntityFromPhysics(pColliderPhysics);
//Now just check if the collider entity is valid
if(pCollider)
{
//Do something to your collider
}
}
}
break;
}
}


Also keep in mind that this event has two parameters:

Code: Select all

//! nParam[0] = const EventPhysCollision *), contains collision info and can be obtained as: reinterpret_cast<const EventPhysCollision*>(event.nParam[0])
//! nParam[1] 0 if we are the source of the collision), otherwise 1.


You can also have a look at this code to see how we use this event to gather all the collision information to send it to C#.

Solved , thanks a lot my friend
