Smooth on the spot Jump

[shiFt]

How would I use

SetUnitFlyHeight

in a periodic so that I can get a smooth on the spot jump, mainly just setting a units height quite high, then falling dramatically.

Well, to make it realistic, you could set the initial increase rate at the maximum rate. Then, decrease the rate as the hero jumps upwards. This way, you can stimulate "gravity".

So far ive got this, it looks ok and i can change the values to perfect it, however the I cant seem to find a way to turn off the periodic, or activate .destroy(), ive tried when .z is under 15 or == 0, but nothing, what is wrong.

The code is the working trigger with the troubling bits commented out.

I'm having trouble seeing what .up has to do with anything.

Your code has much bloat code.

 

[Ayanami]

What does .up do? o.o

And wouldn't KeyTimers2 be a better option for periodic functions with a specific interval that you want to use? Just asking.

 

[Sevion]

I think T32x would be a better choice for this.

 

[shiFt]

I tried using .up to make the .call destroy fire, its just supoosed to record the stages of movement, 0 - cast, 1- unit moves up, 2- unit moving down, 3 -. destroy. How else do you suggest I code it?

Got it working

library UP requires T32,Recycle

        private constant integer SPELL_ID =  'A017'
    endglobals

        private method periodic takes nothing returns nothing
           set .z = GetUnitFlyHeight(t)
         
           if .up == 0 then
                call SetUnitFlyHeight(.t, .z + 15.,.rate - 450.)
           endif

           if .z >= 750. then
                set.up = 1
           endif

                set .z2 = GetUnitFlyHeight(t)
                call SetUnitFlyHeight(.t, .z - 15.,.rate + 550.)
            endif
            
            if .z2 <= 16.and .up == 1 then
                set.up = 2
            endif
            
            if .up ==2 then

Simply use a parabolic function o_o'

y=ax^2+bx+c

Where y is Z, ax^2 is -16t^2 (gravity) + bx (jump velocity) + c (start at).

Then, if t > 0 and z <= 0 then destroy.

You know you're not using your condition, right?

And why are you using actions?

 

[shiFt]

Sorry Sevion can you run that past me again, my maths clearly sucks.

Tooltip
I removed the conditions due to Gtrigger, but what do you mean about my actions?

 

[Sevion]

y=ax^2+bx+c

That's a basic quadratic function.

It creates a curve:

That's not an excuse?

scope KillSpell initializer onInit // requires GTrigger

	globals
		private constant integer SPELL_ID = "A000"
	endglobals
	
	private function Actions takes nothing returns nothing
		call KillUnit(GetTriggerUnit())
		return false
	endfunction

	private function onInit takes nothing returns nothing
		call TriggerAddCondition(GT_RegisterStartsEffectEvent(CreateTrigger(),SPELL_ID),Condition(function Actions))
	endfunction

endscope

That's how you should be working with GTrigger.
