Running, charging, stamina and stances (with a bit of formations)

Look at the section formations https://trac.wildfiregames.com/wiki/Alpha23

Is says that the speed bonus is removed, is that what you are referring to? Because I tried to let units actually run in the formations (visualise an awesome cavalry charge) but, strangely, they only slow down when I try to use the run speed.

What kind of information do you need from the hyrule code? (I talked to exo and while he did adapt it, the core concept remains the same)

Well, I don't *need* anything, but I'm just curious I wanted to see what code they used for the different steps, but if it is basically the same it is okay.

@Freagarach what is your code to set formation to run speed?

Well it does not really matter, as I just saw that in Formation.js "ComputeMotionParameters" only uses the walking speed. So I'll need to tinker with that

[Silier]

Formation.prototype.Run = function()
{
	let maxSpeed = 0;

	for (let ent of this.members)
	{
		let cmpUnitMotion = Engine.QueryInterface(ent, IID_UnitMotion);
		if (cmpUnitMotion) {
			if (maxSpeed == 0)
				maxSpeed = cmpUnitMotion.GetRunMultiplier();
			else
				maxSpeed = Math.min(maxSpeed, cmpUnitMotion.GetRunMultiplier());
		}
	}
	maxSpeed *= this.GetSpeedMultiplier(); <- apply formation speed multiplier

	this.speed = maxSpeed * this.minSpeed; <- this.minSpeed is minimal walking speed of formation
	this.running = true;

	let cmpUnitMotion = Engine.QueryInterface(this.entity, IID_UnitMotion);
	cmpUnitMotion.SetSpeedMultiplier(this.speed);
}

I use something like this

I changed the "ComputeMotionParameters" function to include a check whether "run" is called, to remove duplication But that is not on SVN, so I probably need to use your code in the future

Now is possible ? Or we need more pathfinder changes?

Well, my solution was neither regarding the pathfinder nor UnitMotion, it was regarding a function in Formation.js.

For reference this was my (currently hopelessly outdated) solution:

/**
 * Set formation controller's speed based on its current members.
 * @param {boolean} - whether the run-speed is wanted
 */
Formation.prototype.ComputeMotionParameters = function(run = false)
{
	let minSpeed = Infinity;

	for (let ent of this.members)
	{
		let cmpUnitMotion = Engine.QueryInterface(ent, IID_UnitMotion);
		if (cmpUnitMotion)
			minSpeed = run ? Math.min(minSpeed, cmpUnitMotion.GetRunSpeed()) : Math.min(minSpeed, cmpUnitMotion.GetWalkSpeed());
	}
	minSpeed *= this.GetSpeedMultiplier();

	let cmpUnitMotion = Engine.QueryInterface(this.entity, IID_UnitMotion);
	if (cmpUnitMotion)
		cmpUnitMotion.SetSpeed(minSpeed);
};

But how will work for the user, a hotkeys or mouse command?

The way I implemented it was that at a certain (template-based) range from their targets, the units started running instead of walking. No user input required.
