Actor properties

ACSUtils provides wrapper functions for all actor properties. For every property PropertyName, ACSUtils provides two functions:

type GetActorPropertyName(int tid)

void SetActorPropertyName(int tid, type value)

The only exception is that GetActorViewHeight is a native ZDoom function that takes crouching into account. To access the actual value of the ViewHeight property, use GetActorProperty(tid, APROP_ViewHeight).

Network optimization

All SetActorPropertyName functions first call GetActorProperty and compare the new value of the property to the current one. If both values are the same, SetActorProperty is not called. This automatically optimizes bandwidth use in Zandronum multiplayer. 

function void SetActorHealth(int tid, int Health)
{
	if (GetActorProperty(tid, APROP_Health) != Health)
		SetActorProperty(tid, APROP_Health, Health);
}

Some actor properties are optimized by zandronum itself. However, the set of optimized actor properties depends on zandronum version, and not all actor properties are currently optimized (https://zandronum.com/tracker/view.php?id=1609).

All string properties are compared in a case-insensitive way before being set. This means, for example, that SetActorNameTag(0, "Thing") will not call SetActorProperty if the NameTag property is already set to "thing".
