Week 10 - Heads Up

Another week down with a good amount of progress made. Following up from last week, my primary goal was to finish the player's damage interaction, which meant I had to set up a few extra systems.  First up, we need a way to actually keep track of the player's health, so that means setting up some UI. I created a UI Manager script, defined a basic "UI Screen" to hold shared functionality, and then went about making the HUD from there.  Luckily, unlike many of my past experiences with the art assets I'd been able to find myself, the sprites for the UI chunks I had needed minimal amounts of work in order to get in to "game-ready" state. So, after looking up some basic guides on how to use the UI nodes in Godot, I threw together my replica of the Super Metroid HUD.

Not bad, eh? I'm not planning on implementing grapple beam, reserve tanks, or X-ray visor for this little project of mine, so I left those bits out of my setup. Next step was actually getting those values hooked up to real player stats, which... lead me to rearrange some of my architecture first. Previously, I just had the player, level, and enemies thrown under an empty node for organizational purposes, but I ended up finally making myself a real "Game Manager" script to exercise more control over how the program runs.  Instead of just using Godot's built in "_ready" function to set up values at game start, I introduced Initialization functions to key scripts and had the Game Manager trigger those in correct load order.  In simpler terms, I needed to be able to make sure certain values were set within the player instance before I could hook up my new "Player Status" script and properly connect the HUD to that.

Speaking of Player Status, that script is effectively just a data holder used to keep track of stats. At the moment it holds the player's max and current health, as well as max and current ammo counts for missiles, super missiles, and power bombs, but it will eventually hold data on what power-ups have been collected and what items are equipped. Basically, this thing will be what I eventually turn into save data once I start working on that system.  For now though, it has been properly hooked into the HUD, which updates the relevant fields as necessary. 

Energy tanks are shown/hidden based on what the player's max health is, and the icons for your various types of ammo are set to hidden if you can't hold any of that ammo yet. And of course, this all updates in real time as the player's stats change.

As you might be able to see from the clip above, I also got my i-frame flash working as intended. That one was thankfully as simple as I thought it would be.

For next week, current goals are to get enemy drops working so that there's actually a way to make those numbers go up instead of just down, and also finally maybe make proper hit and death effects for my poor enemies. 

See you next time.
