Hi, i have an isometric game and i want the player to be able to spawn some objects like lets say a cube, but i want to do it on an specific area and also dont let the player spawn objects inside other objects or a wall etc.
I dont know where to start.
is that kind of behavior is what you want?
if you want that kind of behavior, you can start by creating an Actor Class that will be used for the location of the object and the object type. After done creating the class, you need to organize the actor all across the map.
This is my class for organizing the object placement:
...
UCLASS()
class MEDIEVALPANDEMIC_API ATrapPlacement : public AActor
{
....
private:
/** Sample Mesh Component */
UPROPERTY(EditDefaultsOnly, BlueprintReadWrite, Category = "Component", meta = (AllowPrivateAccess = "true"))
class UStaticMeshComponent* SampleMesh;
/** Box Component for placement detection */
UPROPERTY(EditDefaultsOnly, BlueprintReadWrite, Category = "Component", meta = (AllowPrivateAccess = "true"))
class UBoxComponent* PlacementDetection;
/** Invisible Trap class that spawned here */
UPROPERTY(VisibleAnywhere, BlueprintReadWrite, Category = "Trap", meta = (AllowPrivateAccess = "true"))
class ATrap* InvisibleTrap;
/** Trap class that spawned here */
UPROPERTY(VisibleAnywhere, BlueprintReadWrite, Category = "Trap", meta = (AllowPrivateAccess = "true"))
ATrap* RealTrap;
/** Trap Placement Category */
UPROPERTY(EditAnywhere, BlueprintReadWrite, Category = "Trap", meta = (AllowPrivateAccess = "true"))
FName TrapCategory;
};
Later, you just need to do a LineTrace from the character and if the traced actor is an ATrapPlacement (this is the object placement you already spread in the map), then you can check, what is the Category of that placement? is it for the Wall? is it for the Floor?
if it match, you can just spawn the object there. Overall the algorithm I use is like that, if you want further explanation you can just reply this and I will answer it if I can. I’m sorry I can’t upload the project due to the size
