One Last Swing - Tutorial code

tutorial-segments.p8

-- here we modifiy the creation to accomodate
-- the tutorial, where we are gonna show the
-- player which stance beats what

if tutorial > 0 then
  tutorial -= 1
  if tutorial > 0 then
    -- based on which tutorial we are in, set the enemy stance so that is beatable
    -- by the other table inside the players code when we are about to resolve the fight
    local tutorialBeatTable = {MID_STANCE,LOW_STANCE, MID_STANCE, HIGH_STANCE}
    enemy.stance = tutorialBeatTable[tutorial]
    enemy.finalStance = tutorialBeatTable[tutorial]
  end

-- next to all the regular code we inject


	-- we inject tutorial here, basically we wait for the player to
	-- hold the good stance before the clash
	local tutorialGuard = true
	if tutorial > 1 then
		tutorialGuard = false
		-- grab the stance that beats the stance set in tutorial mode 
		-- in create new duel
		local tutorialBeatStance = {nil,MID_STANCE, HIGH_STANCE, LOW_STANCE}
		-- if the player is holding it, trigger the clash state instead of doing the
		-- animations and such

			tutorialGuard = true
			enemy.timeLeftForAttack = enemy.finalStanceHold
			state = "clash"
			music(-1)
			sfx(2)
		end
	end

	-- update opponent's attack timer
	if (tutorialGuard) then
		if (enemy.timeLeftForAttack > 0) then
			-- decrease the time till the opponent attacks
			enemy.timeLeftForAttack -= 1
			-- let them switch around randomly to juke
			if (enemy.timeLeftForAttack > enemy.finalStanceHold) then
				if rnd() > 0.9 then
					enemy.stance = rnd({1,2,3})
				end
			else
			-- enemy step back time
			-- here they already hold their final stance
				enemy.x += 0.1
				enemy.stance = enemy.finalStance
			end
			-- since some enemies are to fast to step back a correct ammount
			-- (more than 1 px), let the blade also flash so we can see the
			-- attack coming
			if enemy.timeLeftForAttack < 10 then 
				enemy.shineBlade = flr(enemy.timeLeftForAttack%2)
