--[[
These are the default implementations of the override actions.
If you want to add custom logic into your game you can define a "proc.lua" in your map dir.

The following functions are also available via our C library:

void c_update_player_pos (dx, dy)
boolean c_player_can_move (dx, dy)
boolean c_enemy_can_move (id, dx, dy)
c_spawn_enemy (x, y)
c_destroy_enemy (id)
c_trigger_win()
c_trigger_loss(msg)
c_fatal(msg)

--]]

require "include.constants";

---@param pressedKey number
function onKeyPress(pressedKey)

    dx = 0
    dy = 0
    if (pressedKey == KEY_W) then
        dy = -1
    elseif pressedKey == KEY_A then
        dx = -1
    elseif pressedKey == KEY_S then
        dy = 1
    elseif pressedKey == KEY_D then
        dx = 1
