Non-linar resource usage.

[JakeMilo]

Good Day,

I have been working on a side project with the authoring kit and have encountered a small problem.

The progression system I am trying to implement has a two tier cost system, and the cost system is also non-linar.

The first set of costs are:

rank cost (total cost)
0 0 (0)
1 10 (10)
2 15 (25)
3 20 (45)
4 25 (70)
5 30 (100)

The second set of costs are:

rank cost (total cost)
0 0 (0)
1 5 (5)
2 10 (15)
3 15 (30)
4 20 (50)
5 25 (75)

Using thread necromancy I found this:

Which helped resolve the second set of numbers. However, the first set of numbers are behaving strangely.

<!-- Each career skill point that is allocated by the user costs the appropriate XP -->
	<eval index="5" phase="Traits" priority="10000">
      <before name="Calc resLeft"/>
      <after name="Bound trtUser"/><![CDATA[
	    doneif (field[trtFinal].value = 0)
	    doneif (tagis[Skill.Career] = 0)
		var traitlevel as number
		var traitcost as number
		var finalvalue as number
		traitlevel = field[trtFinal].value
		traitcost = 5
		finalvalue = traitcost / 2 * (traitlevel * traitlevel + traitlevel)
		hero.child[resXP].field[resSpent].value += finalvalue
      ]]></eval>
	  
	<!-- Each non-career skill point that is allocated by the user costs the appropriate XP  -->
	<eval index="6" phase="Traits" priority="10000">
      <before name="Calc resLeft"/>
      <after name="Bound trtUser"/><![CDATA[
		doneif (field[trtUser].value = 0) 
	        doneif (tagis[Skill.Career] = 1)  
		var traitlevel as number
		var traitcost as number
		var finalvalue as number
		traitlevel = field[trtFinal].value
		traitcost = 5
		finalvalue = traitcost / 2 * (traitlevel * traitlevel + traitlevel)
		hero.child[resXP].field[resSpent].value += finalvalue + 5
      ]]></eval>

With the finalvalue + 5 in, the first and second rank cost 10 each and then increases in 5 increments.

Without the doneif (field[trtUser].value = 0) line, it causes the 0 value of the skill to cost 5 each.

Was wondering if anyone could help tell me what blindingly obvious mistake that I am making is?

I also tried this:

var traitlevel as number
                doneif (field[trtFinal].value = 0)
	        doneif (tagis[Skill.Career] = 1)
		var finalvalue as number
		traitlevel = field[trtFinal].value
		finalvalue = (2.5 * traitlevel * traitlevel) + (2.5 * traitlevel) 
		hero.child[resXP].field[resSpent].value += finalvalue - 5 -->

Which is the excel graph formula (ignoring the 0 value), which breaks in similiar ways.

In this case, your first set of costs are not quite the same formula.

The formula for your first table is 2.5x^2 + 7.5x

So in HL:

traitcost = 5
finalvalue = (traitcost / 2 * traitlevel * traitlevel) + (traitcost * 3/2 * traitlevel)

Good Day,

Thanks for the rapid response.

It, of course, works.
