Construct a Hero role
Optional allowTrue if the hero can jump infinitely often when in mid-jump
Optional mustDoes the level end immediately if this hero is defeated?
Optional numUse 2 to enable double-jumps, etc.
Optional onCode to run on any change to the hero's strength
Code to run on any change to the hero's strength
Optional strength?: numberThe hero's strength (default 1)
collisionRules lets us turn off collisions based on the roles of two actors. We do this with two sets. If A's second set contains an entry in B's first set, then we disable the collision. We also do this symmetrically with B and A. In essence, this means that the first set lets a Role say "here are special things about me", and the second set lets a Role say "I don't collide with things that are special in these ways."
The second set: properties that this role won't collide with
The first set: properties of this role
For tracking if the game should end immediately when this hero is defeated
Optional onCode to run when the hero's strength changes
Code to run when the hero's strength changes
Readonly prerenderTasks to run before every render
Optional actor: ActorTime until the hero's invincibility runs out
Strength of the hero. This determines how many collisions with enemies the hero can sustain before it is defeated. The default is 1, and the default enemy damage amount is 2, so that the default behavior is for the hero to be defeated on any collision with an enemy, with the enemy not disappearing
This actor ignores collisions with Heroes
Indicate that the current Role should not ignore collisions with some other role
The role that should not be ignored
Code to run when a Hero collides with another Actor
The Hero is the dominant participant in all collisions. Whenever the hero collides with something, we need to figure out what to do
Other object involved in this collision
The Hero is the focal point of a game. While it is technically possible to have many heroes, or invisible heroes that exist just so that the player has to keep bad things from happening to the hero, it is usually the case that a game has one hero who moves around on the screen, possibly with jumping and crawling.
