aiwana engine basics

• player movement
• accurate moving solids
• accurate moving jump-through platforms
• saving/loading
• touch saves and bullet blockers
• automatic camera that snaps to screen & example smooth panning camera
• large number of customisable engine settings
• crisp pixel scaling filter that doesnt make the game look blurry
• thought-out folder structure for asset list separating level objects and code. i also tried to signpost code that the user can freely edit and what is advanced system code

standard "jtool" gimmicks

• water2 & water3
• vines
• jump refreshers
• gravity flippers
• platforms and "snapforms"

advanced music system

• separate options for music, sound effects, master volume
• automatic loading and unloading of audio files
• crossfading between tracks
• song title display in pause menu
• see code/scripts/musicScripts for use and a few other convenience functions

easy to modify menus

• buttons scale to the size placed in room editor
• an invisible menu "cursor" automatically navigates any buttons placed in a room
• the menus are minimilastic visually, to change the style see draw events:
  • code/objects/menu/parents/MenuButtonParent
  • code/objects/menu/parents/ButtonOptionParent
• functions for generating buttons to edit game options:
  • buttonTemplateToggle(option, textTrue="On", textFalse="Off")
  • buttonTemplateSlider(option, isPercentage=true, increment=0.1, low=0, high=1)

input manager

• any number of binds for each action (or "verb")
• see code/scripts/inputScripts:
• inputInit() generates default binds, add or change inputAddBind(verb,button) calls to change
• checking if a button is held/pressed/released is checked via the verb, not the button. for example u would type inputPressed("shoot") instead of inputPressed(ord("Z"))
• for examples see code/objects/player/Player (step event)

gamepad support and button rebinding

• automatic button name lookup
• can detect dualshock 4 and maybe other types of playstation controllers. not sure tho i only have one pad so i cant test anything else
• two binds are automatically swapped if there is a collision
• should be easy to add new bindable buttons - its done by a list of verbs in code/objects/menu/rebinding/ControlsMenuButtonSpawner

what do i want to include in the future?

• an example tileset or two
• setting to disable gamepad
• setting to change gamepad thumbstick deadzone
• more comments and documentation

what is not in the engine?

• anything that comes down to "style"
• difficulty settings
• society has moved past the need for slippery ice blocks

known bugs

• snapform is sometimes not snapped to when moving down and player is jumping up (relative to gravity)
• adding a new bind to inputInit() will be ignored if there is already a saved controls file
  • for now, delete %localappdata%/game_name/controls
