The start of a HUD
|
The functionality for it was easy to program and no real complexity in the code was needed. Though some problems occurred while doing it, these problems occurred since I was tired while programming them. This post will mostly contain the problems that occurred while trying to implement the system. The main problem was how I was going to make the life bar move with the screen. And even though I already had a mini-map in the HUD I did not think of just adding it into a new view. I currently have three different views in the program. One is the view for the main screen where all the game play is showed. An other view is for the mini-map, this is a separate view from the life-bar since the mini-map view is scaled down and its origin is in the top left corner. Therefore I had to make a separate view for the rest of the HUD. To get the life-bar to change accordingly to the players health only a couple of checks on the players health is needed. Right now these checks are made each frame. Though I will make it so that these checks only are called once the player takes damage, or gets healed. So if the players health is equal to a certain value the sprite will change accordingly. I also started to implement a rage system which is supposed to increment each time an enemy is killed. This rage will be used to fire a projectile which pushes/knocks enemy units back towards the angle of which the projectiles direction is. In addition if the rage-bar (which is not currently implemented) gets filled the players projectile will get changed to an offensive one for a set duration which makes it so that the players projectiles deals damage. A problem with getting the rage system to work is that at first I made a new one in each enemy which resulted in mayhem. I had to do this since I was not aware of that it was the play state that was going to keep track if the enemies were alive or not. Before I had it so that each enemy was aware of its own health. This was a problem since I had to return values from the enemy when it died, and I was not able to get it to work. So I changed it so that the test-state checked all the enemies health if they were not dead, and if their health is 0 or below 0 I set them to dead and add rage to the player. An other problem that was the root cause of many other problems is that the player is not a separate class at the moment. I will probably change this after the beta, at this point and time I do not have the time to convert the amount of code for the player to a separate class. Hopefully this blog post had some value in it, even though it was mostly about troubleshooting.  |
