Double cast, no mp cost for second skill

[ragnorak6608]

So I am looking to use the notetag that Yanfly provided on his site for dualcast, it is as follows

Spoiler

<Custom Action Start Effect>
// If a chained action is stored...
if ($gameTemp._chainAction === undefined) {
// ...then set the action to the user's current action.
$gameTemp._chainAction = user.currentAction();
} else {
// ...then clear the stored action.
$gameTemp._chainAction = undefined;
}
</Custom Action Start Effect>

<Custom Action End Effect>
// If a chained action is stored...
if ($gameTemp._chainAction) {
// Set the 'action' variable to the chained action.
var action = $gameTemp._chainAction;
// Check if the action exists, is a skill, and is a magical attack.
if (action && action.isSkill() && action.isMagical()) {
// Get the skill used for that action.
var skill = action.item();
// Check if the user can pay the skill cost.
if (user.canPaySkillCost(skill)) {
// Check if the battle system is DTB.
if (BattleManager.isDTB()) {
// If it is, add the action to queue.
user.setAction(0, action);
// If the battle system isn't DTB...
} else {
// ...make it a forced forced.
BattleManager.queueForceAction(user, skill.id, -2);
}
}
}
}
</Custom Action End Effect>

<Custom Remove Effect>
// Clear the chained action effect.
$gameTemp._chainAction = undefined;
</Custom Remove Effect>

I wanted to change it into a state that when the user reaches 100 TP, they enter a dualcast state where you can casts 2 magics for the cost of 1.


I have the conditions and separate state to activate the dualcast, but can figure out the script call to change a skill's cost temporarily.  I know I would need to set the base cost to a variable, change the cost to 0, and then set it back to the base.

I think the thing would be more of a code on the skill to change its cost to 0 when using doublecast.

Here is what i have so far:


This is the passive state that triggers DualCast

Spoiler

<Custom Turn Start Effect>
if (user.tp === 100) {
user.dualcastturn = 3;
$gameActors.actor(2).gainTp(-100);
$gameActors.actor(2).addState(72);
user.setStateCounter(72, user.dualcastturn);
}
</Custom Turn Start Effect>

This is the state applied when reaching 100 TP 

Spoiler

<Custom Action Start Effect>
if (user.dualcastturn > 0) {
if ($gameTemp._chainAction === undefined) {
$gameTemp._chainAction = user.currentAction();
} else {
$gameTemp._chainAction = undefined;
} }
</Custom Action Start Effect>

<Custom Action End Effect>
if (user.dualcastturn > 0) {
if ($gameTemp._chainAction) {
var action = $gameTemp._chainAction;
if (action && action.isSkill() && action.isMagical()) {
var skill = action.item();
BattleManager.queueForceAction(user, skill.id, -2);
user.dualcastturn--;
} } }
</Custom Action End Effect>

<Custom Turn End Effect>
if (user.dualcastturn === 0) {
$gameActors.actor(2).removeState(72);
} else {
user.setStateCounter(72, user.dualcastturn);
}
</Custom Turn End Effect>

<Custom Remove Effect>
$gameTemp._chainAction = undefined;
</Custom Remove Effect>

would there be a way to enter it into the state notetags? I know yanfly's skill core has custom mp cost, but that needs to be applied to each skill. I would want it to check the skill about to be cast, change its cost to 0, cast the ability, and then revert it back to default cost.

could tweek my red mage for that i think
<Instant>
<Follow Action>
Add State 39: user
</Follow Action>

State 39
remove turn end 1~1
remove end of fight
<Cancel Instant Skill: x to y>
then if u just add in
Sp-param MP cost rate: 0%
2nd spell should cost nothing
