game object properties

[Arctenik]

should probably make some actual plans for what properties objects will be able to have and how they'll work particularly wrt unique behaviors

one specific thing that i'll definitely want at some point is z index for sprites bc at the very least the net should have a front and a back part that the ship goes between

some other things i'm gonna want are multiple sprites [EDIT: done], some way to switch between them, and some way to make the object move [EDIT: done]

[Arctenik]

i think i'll probably have a way to make simple scripts with json but maybe also have it so javascript files can be included in a level?

there'll probably various events that you can attach handlers to and i think maybe there'll be a property where you can put a sequence of actions to be executed repeatedly which could be useful for objects that move along a fixed path

[Arctenik]

although i'm not trying to precisely emulate aqua grabber i would like everything that existed in it to be possible in astro snatcher without too much trouble so i think it might be good to list the objects from aqua grabber and their behaviors

[Arctenik]

clam:

• has a "sleep" state induced by ship hovering nearby and ended by ship bumping something
• while asleep, pearl can be collected at intervals
• a random one has a black pearl

giant clam:

• holds grand pearl
• pearl-shaped rock attaches to it and moves to a certain position
• when grand pearl is picked up w/o rock:
  • ship drops pearl, which moves back into clam
  • ship is drawn into clam
  • ship is propelled out with depleted air

worm substrate:

• creates a worm when bumped

worm:

• while on the ground, moves back and forth and eventually disappears

fluffy:

• moves in a fixed path
• when colliding with a claw carrying a worm, replaces the worm as the carried object
• while carried, influences the ship's movement

mullet:

• moves in a fixed path
• when colliding with a claw carrying a fluffy, replaces the fluffy as the carried object
• while carried, influences the ship's movement

soda barrel:

• decrease a soda variable when collected by the net

soda seas flora:

• stop being a solid barrier in respones to lowered soda variable

coin pile:

• multiple but limited coin objects can be collected from it

crab:

• moves back and forth removing coins from the coin pile; the coins exist as collectibles while being taken away
• comes out holding an emerald if allowed to take all the coins

pufferfish:

• increases in size when the ship comes near
• knocked away when bumped by the ship
• returns to original size and position when the ship leaves
• doesn't collide with the claw

guardian pufferfish:

• moves in a fixed path, but can be temporarily knocked slightly out of place if bumped by the ship

giant pufferfish:

• repeatedly increases in size while drawing ship toward it and then returns to original size

re: sequence of actions to be executed repeatedly, maybe there should just be an "onStart" event [EDIT: done] and some sort of generic "loop" function [EDIT: done]? also there should ofc be a way to stop loops

[Arctenik]

have added multi-sprite support, onStart, looping, and movement

[Arctenik]

I wonder if it'd be useful to be able to control what objects can collide with what other objects, potentially using some sort of "collision group" system

[Arctenik]

for movement physics maybe i should just have properties that specify multipliers for the two axes?? um and then also i should probably have a property to determine whether the object collides with solid objects and one that determines how much it bounces when it does so
