HUD Panel
The page relates to the HUD panel visible in the stage scene.
The HUD panel is a UI panel placed on the right side of the screen. It consists of several elements and their numbers depend on selected game mode.
Going from the top, the first element is the left enemies panel. It is a separate UI panel which contains many the same looking icons representing the black robot with red eyes. They indicate how many enemies left to spawn before depleting all of waiting instances.
After spawning another enemy, one of the icons disappears to update current number of enemies waiting in a queue. If all the icons disappear, then it means that no enemies left in a queue and this was the last one to spawn.
Number of these icons corresponds to the number of enemies detected from the read stage data, however cannot be more than 20 (which is the maximum). In case when number of enemies in the stage exceeds 20, then the icons start vanishing from the moment when an enemy was spawned and there are 19 left in a queue.
The next element is another UI panel which contains counters of the players' lives. The first one is dedicated for the first player (icon of the orange robot) and the second one, for the second player (icon of the green robot) which is visible only after selecting the 2 player mode.
The last element is also a separate UI panel, but this time is dedicated to the current stage counter. It contains the red flag icon and a counter representing number of the currently playing stage.
