Mathematic Help

[jnZ]

Ppl i need help, i got a spell that sends a unit to a targeted location and the unit is supposed to explode (die) as soon as it arrives the location. i want to add an expiration timer that kills the unit if it arrives at the location. all i need now is the mathematic part for the expiration timer duration. the movementspeed of the unit is 300.

you know something like Distance between point X and y / movementspeed, thats all i could come up with but it didnt work.

What's wrong with creating a region and detecting when the unit enters the region?

MPI/MPU crap

Why don't you just slide the unit? Distance / Timer interval gives you the slide distance for it to reach it's destination after 1 second.

 

[MoonSlinger]

( Distance between point X and Y ) / movementspeed
Nothing wrong with the maths.

However, WC3 units do not have a habit of moving in a straight line , they like to twist and curve.... If you want them to move and explode correctly, you need to slide them.

Also if your particular unit is not flying, you need to take into account blockade... like trees or other doodas

> it didn't work.


Well, "it doesn't work" is not a very good problem description.
"Time = Distance / Speed" is correct.

On a related note, problems with triggers are best helped with by posting said triggers.

        Custom script:   call RemoveLocation( udg_TargetLoc )
        Custom script:   call RemoveLocation( udg_CasterLoc )

i think the sheep explodes to early/late because its created at a random facing and has to turn before it moves. how to create it so it faces the targeted location?

EDIT: the unit is flying so nothing should be able to block its way.

btw another thing would be rly helpful here. whats the mathematic for setting the flying height of the sheep from 100 to 0 so its reaches 0 when it arrives at the targeted location. (the formula for the rate)

 

[AceHart]

Rate is the height per second.
I.e. to go from 0 to 200 with a rate of 50, you need 4 seconds.

thanks that helps me out but still how to set the facing to the targeted location? facing of the casting unit wont helo because they sometimes cast and still dont face the targeted location

 

[Larcenist]

Angle between points. Position of (triggering unit) and Target point of ability being cast.

 

[jnZ]

thanks that worked, now ill only have to work on the flying height rate

EDIT: its the following:

Animation - Change CreatedUnit flying height to 0.00 at (Current Flying Height of CreatedUnit / Distance Between pont X and Y / Movementspeed of Created Unit)
