"Fixed enemy health bar,  Added statue enemy"

Fixed enemy health bar:

    Just fixed this small issue I noticed when I was testing the new statue enemy. The issue being that the health bars above enemies heads would appear and disappear at the wrong time. I intended for the health bar to appear when the player is looking more or less directly at the enemy. What actually happened was the health bar would appear from the far left of the screen to the correct spot on the right. the problem was that I was just using the wrong conversion node from screen to world. I found the correct node from this thread.

 Added statue enemy:

    From the design doc I was told to make an enemy that: "These do not move on patrols they stay in one location and wait till attack come within range". Additionally during a meeting I was told that they would be stationary on a pedestal until they jump on and off to attack the player. This made me learn about AI jumping. 
    I followed this video to make the original smart nav links. Doing this allowed me to specify things like how long the jump should last, which I thought would have been taken care of by the engine but apparently not. Other than that the jumping was relatively simple to do. 
    The rest of the AI was pretty similar to the basic melee enemy that we already had. Just that when the player is lost, the statue will return to the pedital and rotate to its original rotation. The last thing that I did was to generalize the attack task to be usable on any enemy. This simplified things a lot and I am quite happy with it.

Polishing the Foundation

     This sprint was relatively uneventful; mainly cleaning up the existing foundational elements of the game (the first person character and spell component) and continuing to improve the necessary elements of the game like the pause screen. Player Character & Spells      The improvements to the player character come in two parts; the ability to have, use, and change spells, as well as interaction via an interface. Both of theses are as simple as I could make them. Utilizing inheritance from USpellBase using the spells is only really a single line, and changing out the spells we can use the NewObject factory to make a new spell very simply. FirstPersonCharacter.h FirstPersonCharacter.cpp      As for the interaction interface, it only consists of two functions right now, one to fire an interaction event and one to check if the object can be interacted with. This second function is used mainly to show UI on the player's screen like...

Progress Update #13

  Niagara Asteroids in UE4     These past few days I have continued work on asteroids. Only that now I have ditched instanced static meshes in favor of getting my hands on the new-ish Niagara particle system.  Learning Niagara     I have decided that since this is an entirely new subsystem of the engine I would do everything in blueprint first, then transition everything to C++ when I knew it was working reliably. Additionally, because Niagara is still relatively new, the official documentation is sparse if existent at all. So with most tutorials at this time geared towards blueprint implementation, starting in blueprint will give me the highest likelihood of finding a solution to any problems I may come across. The Niagara Workflow     The first thing I learned about Niagara is that the workflow has changed significantly from what cascade was. Where in cascade (to my limited knowledge) you worked in one particle system where e...

A New Chapter

Image
     This week has presented the biggest change probably since the release of Mini Solar System; I was offered a full-time position as a junior programmer at Studio 369 which I was happy to accept. I start on Monday and I couldn't be more excited to work with the team there! However, this did mean though that my priorities shifted quite instantaneously. I went from working full-time on "RPG_Game" to preparing for this new job. This mainly meant getting up to speed on networking as that is the one area of Unreal Engine I feel I have a lack of knowledge in (I'm already proficient in UI, AI, gameplay, materials, and general backend work), and since 369's specialty is networking I figured I would come prepared. I did do a little work on "RPG_Game" but it was minimal just to tie up some loose ends. Unreal's Multiplayer Framework      As explained by the Unreal Engine documentation, "multiplayer programming [is] inherently more complex than programmin...
