SandWyrm

Special enemy party layout

This enemy is meant to function in tandem with another: the SandWyrmTail.

The SandWyrmTail should always be present when this enemy is not stopped and the battle should always starts with both. This is enforced by the EnemyCheck logic and this enemy's pre move action logic. They also have each a VenusBattle that references each other so they can have synchronized and consistent animstate logic.

In this configuration, the SandWyrmTail is more an instrument to this enemy even if they are both completely separate enemies. The action logic of either assumes the presence of the other with the only exception being when the SandWyrmTail dies where its EventDialogue will inflict Flipped to SandWyrm for 2 main turns. This effectively will make them not act for 1 main turn due to how DoAction will skip the action if more than 1 main turns are left on it (but on the next main turn, the condition gets removed and they get to act again so overall, it's 1 main turn of no action).

At that moment, the SandWyrm is stopped for a main turn and the SandWyrmTail removed since they died. However, the moment the SandWyrm gets to act again on the next main turn, they will summon the SandWyrmTail again. Essentially, killing the tail will only remove it temporarilly from the battle.

This setup is tore down on SandWyrm's EventDialogue when it dies. In that case, both it and the SandWyrmTail will be killed together if the SandWyrmTail still exists by then (it is possible it didn't since it's possible it died and SandWyrm couldn't summon it).

Assumptions

It is assumed that this enemy has an eventondeath set to the proper EventDialogue because this EventDialogue will allow the SandWyrmTail to die with this enemy.

data usage

At the start of the action, if data is null or empty, it's initialised to be 1 element with a starting value of 0.

• data[0]: The value determines the enemy to summon in the enemy summon move and it toggles between 0 and 1 after the summon each time the move is used. A value of 0 (the starting value) means a Strider will be summoned while a value of 1 means a DivingSpider will be summoned

StartBattle special logic

This enemy features special logic during StartBattle before and after it is loaded.

Before the enemy is loaded (EnemyCheck)

If StartBattle was called with any elements of enemyids containing this enemy or SandWyrmTail, the entire enemyids is overriden to be {SandWyrm, SandWyrmTail}.

After the enemy is loaded (enemy party setup)

If enemydata contains this enemy, a VenusBattle is added to the first 2 elements of the enemy party where the parent is the other enemy and the target is themselves. Since the EnemyCheck logic already enforced the layout of the enemy party, it effectively means that:

• This enemy gets a VenusBattle SetUp with a target of themselves and the parent being the SandWyrmTail
• The SandWyrmTail gets a VenusBattle SetUp with a target of themselves and the parent being this enemy

This means that each have a VenusBattle that checks each other to make sure they have matching animstate and animations. It allows to keep them in sync visually in a consistent manner.

This part of the logic also changes the battlepos of this enemy and the SandWyrmTail:

• This enemy: (3.0, 0.0, 0.0)
• The SandWyrmTail: (5.9, 0.0, 0.0)

HardMode changes

HardMode being true does the following changes:

• In the bubble spray move, the DoCommand call (which is a TappingKey) has barfill decrease 25% faster each frame. However, this change doesn't affect anything if mashcommandalt is true making the command a SequentialKeys

Move selection

3 moves are possible:

1. A single target bite attack
2. A party wide bubble spray attack
3. Summons a new Strider or DivingSpider enemy

The decision of the move to use is based on odds, but those odds changes if InputIO.IsEditor is true which can't happen under normal gameplay (it would mean the game is being ran inside the Unity editor). Here are the odds:

Move	Odds in Unity player	Odds in Unity editor
1	3/6	3/7
2	2/6	4/7
3	1/6	Never used

However, if move 3 is selected and there's already 3 or more enemy party members, a continue directive is issued on the enemy actions loop which restart the entire action logic and effectively rerolls the move selection.

Pre move logic

There's logic that will always be done at the start of the action. It's in 2 parts done in order.

SandWyrmTail summon

If SandWyrmTail isn't in enemydata, it is summoned back by doing the following (normally happens when this enemy acts after the tail died):

• ShakeScreen called with an ammount of 0.05 and a time of 1.35
• animstate set to 100
• checkingdead set to a new SummonEnemy call to summon a new SandWyrmTail enemy with type Raise at (5.9, 0.0, 0.0)
• Yield for a frame
• The SandWyrmTail has their height and initialheight set to 0.0
• Yield for 1.35 seconds
• Prefabs/Objects/WaterSplash instiantiated at (5.9, 0.0, 0.0) and destroyed in 0.75 seconds
• Yield all frames until checkingdead is null (the summoning completed)
• size set to 1.75
• cursoroffset set to (-1.75, 4.45, 0.0)
• The local startstate and basestate set to 0 (Idle)
• Yield for 0.5 seconds

Changing startp

The following logic always happen if there's exactly 2 enemy party members (this essentially restores the startp this enemy had before it summoned an enemy):

• MoveTowards (3.0, 0.0, 0.0)
• Yield all frames until forcemove is done
• startp is set to this enemy position except the y component which is set to 0.0
• flip is set to false

Move 1 - Bite attack

A single target bite attack.

BasicAttack calls

#	Conditions	enemyid	walkstate	attackstate	attackstate2	damage	offset	property	shake	delay	sounds	dontgettarget
1	Always happen	This enemy	1 (Walk)	100	101	3	(3.25, 0.0, -0.1)	null	0.0	Random between 0.65 seconds and 0.85 seconds	TidalWormBite	false

Logic sequence

• checkingdead is set to the BasicAttack 1 call
• Yield all frames until checkingdead is null (the BasicAttack 1 call completed)

Move 2 - Bubble spray

A party wide bubble spray attack.

nonphyscal set to true

This move always sets nonphyscal to true which affects the effects of the FrostBite, SpikeBod and PoisonTouch medal if equipped on the target.

DoCommand calls

#	Conditions	timer	commandtype	data
1	None	165.0	TappingKey	{4.0, 8.0, 0.81, 1.0} if hardmode is false {4.0, 8.0, 1.251, 1.0} if hardmode is true

1: Due to the clamping logic related to this value, it means that the decrease value per frame is 0.005 * the game's frametime when hardmode is false and 0.00625 * the game's frametime when hardmode is true. Effectively, it means that hardmode being true makes barfil decrease 25% more per frame

PartyDamage

#	Conditions	caller	damage	property	block	jumpheight	spinammount	jumpevenonblock	overrides
1	Always happen	This enemy	3	null	true only if barfill is at least 0.9 after DoCommand 1, false otherwise	0.0	Vector3.zero	false	null

• DoCommand 1 call happens
• All player party member whose hp is above 0 has their y spin set to 20.0 and their animstate set to 11 (Hurt)
