This a personal project that I created using a udemy course, Unreal Engine 5 C++ Developer: Learn C++ & Make Video Games. When I completed the course it was for UE4. I adapted the course for a top down shooter.
The player moves around using wasd and controller support set-up. When the player rotates the player's pawn on a swivel. The player has a gun with infinite ammo.
The gun uses a projectile system over a raycast. This is to have a particle system that shows the bullets flying. The spawn for the gun fires out from the player's muzzle on the gun. Doing this way means that the when the player moves the gun sways due to the animation that is used on the player.
if (GetWorld())
{
FActorSpawnParameters SpawnParams;
SpawnParams.Instigator = GetInstigator();
AProjectileBase* Bullet = GetWorld()->SpawnActor<AProjectileBase>(ProjectileClass, MuzzleLocation, MuzzleRotation, SpawnParams);
if (Bullet)
{
FVector LaunchDir = MuzzleRotation.Vector();
Bullet->FireInDirection(LaunchDir);
}
}
The bullets use projectile movement to fly through the air and when they collide with a pawn they damage that pawn.
The Ai looks for the player. If the Ai sees the player then walks over and shoots at the player.
When the player destroys an Ai object they drop a health pack, this is to create a risk/reward to the player to pick up health and thus may run into more enemies. After checking that each cast is working the pick up simply adds health to the player and then destroys.
{
APlayerCharacter* PChar = Cast<APlayerCharacter>(OtherActor);
if (PChar == nullptr)
{
UE_LOG(LogTemp, Error, TEXT("PChar not casting"));
return;
}
else
{
ATDPlayerController* PController = Cast<ATDPlayerController>(PChar->GetController());
if (PController == nullptr)
{
UE_LOG(LogTemp, Error, TEXT("PController not casting"));
return;
}
else
{
UE_LOG(LogTemp, Warning, TEXT("Overlap worked"));
PChar->AddHealth(Health);
Destroy();
}
}
}
The main loop just works on checking if the player is dead and then displaying the time in seconds.
This course really helped with C++ coding for Unreal. I learned the structure for the different systems of unreal and it was really fun to create the game.
