Some Other Things from the UMG Tutorial

• I think that it is important that we stop and take a look at some of the built in components of games we have been working on.
• In general, I would like to be able to build an ammo spawner.
• I want to understand the pickups better.
• Start off by looking at BP_Pickup_Child_Damage
  • BindEventToOnPickedUp is reasonably simple.
    • This adds an event to the play when the child is picked up.
    • It just happens to be the event that destroys the actor (healt h pickup) and applies damage to the player.
• I modified the BP_Pickup_Child_Health actor
  • I added a float, PowerUpValue
    • I exposed this to the public
    • And used this time -1 to send to the damage function.
  • This is just to make the blueprint just a little more flexible for my use.
• By the way, notice that these are both children of the PB_Pickup_Parent
  • I suppose we could have modifed this but that doesn't make as much sense to me.
  • What does this actor provide?
• How do you spawn something?
  • The Character_FirstHourUMG does this.
  • Look at The blueprint.
  • Spawn Projectile.
  • SpawnActor is the key here.
• Ok, so the projectile
  • Look at BP_Projectile
  • Nothing special there. Good.
• So I want to build my spawner.
  • BP_HPMaker

  • private:
        Actor * MyChild
    public:
        float HPValue 
        float RespawnRate
    
    
    constructor:
        MyChild  = nullptr;
        ChildWasPickedUp();
        return;
    
    ChildWasPickedUp() {
        if MyChild != nullptr
           SetDelay(RespawnRate);
           MyChild = SpawnActor(BP_Pickup_Child_Health)
           MyChild->PickedUpEvent(ChildWasPickedUp);
           return;
