Destructable terrain - a few questions

[Falafelkorv]

I just got an idea: Destructable enviroment in WC3.
I want to start with the terrain. I know how i gotta do it. I gotta use a "create crater deformation" trigger. Three problems:
I need a event that fires when a, for example, rocket hits the ground. How?
I also need something to know WHERE the rocket hit the ground. How?
And how do i make the crater "Walkable"? I mean so that i wont be running 3 feet over the visible ground.

1) You will need a custom rocket to fall off the sky. The rocket will be a dummy unit. A trigger tha runs periodically to set the rocket's flying height will check if the current height of the rocket is 0 (Real comparison). If it is, then kill the rocket dummy and perform the Environmental change of deformation.

2) Don't get what you mean by "Walkable". Craters don't change the ground's pathing, they are normally "walkable", as the default ground is.

 

[Falafelkorv]

Cant you change the pathing with deformation? You just walks over the crater like it wasnt there.
Do you know a tutorial on how to do 1)?

[Pharaoh_]

It depends, what do you want to make with 1)? If you are after a unit, firing rocket missile as a result of an attack (or attack ground), then you need a custom missile system. If you are after a single ability that fires a rocket up the sky and brings itself back on the ground, I can do it for you.

 

[Falafelkorv]

Hmm... Is it possible to put this system on a tank etc? With a direkt hit?

 

[Falafelkorv]

Bump
I would really like this system. I want to use it on any explosive damages. Please help me guys.

Well, for bomb hits a target you can use, either the trigger you're making the spell, when you change it's height to 0 wait 1 sec and start or to use a trigger which will follow the height of the bomb, when it reaches 0 it will start. Here:

• Events
  • Time - Every 0.03 seconds of game time
• Conditions
• Actions
  • If (All Conditions are True) then do (Then Actions) else do (Else Actions)
    • If - Conditions
      • (Current flying height of (Your Bomb)) Less than or equal to 0.00
    • Then - Actions
    • Your Actions
    • Trigger - Turn off Your Trigger
    • Else - Actions

For the point of the bomb if it's a spell then use Target Area of Ability Being Cast, or if it's a point then set a Variable to that point and use it. As for the Walkable craters, well if they don't walk down to it, use animation change unit's Flying Height to -how much the crater is deep. Hope it helps

I've never been able to get crater deformations to work right, it seems as though it appears as a deformation the game doesn't recognize the change in the ground as an actual change of it's Z, thus units ignore it when walking over it.

Didnt really get that. Also, i would need this on a tank, that fires directly on the target.
Isnt there a way to get coordinates of where the attack hit the ground?
Please make a map with this in to show me.

If it is a spell then the point would be Targeted Point of Ability Being Cast or Position of Targeted Unit of Ability Being Cast, or if it's a normal attack, then Position of Attacked Unit. For the cooldown of the hit well, either put a random wait but it will not be correct if your target is close or calcuate the distance and add a wait depending on the distance between the Attacking Unit and the Attacked. As for what I wrote, if you're using a Custom spell that, well lets say a bomb that falls somewhere on the map, and if that bomb is a dummy, you can use it's height to calculate when it's going to hit the ground. Could make a map or paste a trigger but say for what do you need it, for a normal attack or for a spell or for a dummy? Hope it helps

 

[Falafelkorv]

Thanks The_DooM!
That helped. And yeah, please make a map for the dummy thing. I have never used them, so ill probably learn some from it!
Gonna try the "Targeted Point of Ability Being Cast or Position of Targeted Unit of Ability Being Cast" thing tomorrow.

np will see if I'll make the map.

 

[Falafelkorv]

Hmm, thats bad. I cant find a way to make it explode upon hit. It triggers once the order is given. How do i manage this?

//falafelkorv

 

[The_DooM]

Add a wait depending on distance between the unists. It depends on how fast the missile speed is. Lets say, 600 missile speed and if the target is 800 from the caster, it will be 1.2 sec. Here:

• Wait ((Distance between (Position of (Casting Unit)) and (Position of (Targeted Unit of Ability being cast))) / 600(missile speed)) seconds

Hope it helps

 

[Falafelkorv]

Thanks!
Ill try it tomorrow, hope it works!
You have any idea on how to the units walk down into creater deformations?

//Zelzahim

 

[The_DooM]

Sorry, no, but try setting the unit's height to - when he enters a crater.

 

[Falafelkorv]

I cant find those wait options:/
Please make a map with them in it.

//Zelzahim

 

[The_DooM]

Put Athimetric then in the first put distance between Target ect and Targeted, in the second put your missile speed of your ability, let's say 600. Look at your ability in the Object Editor and see it's missile speed, then put it in instead of the 600. Here:

 

[Anachron]

If you really want to do this you have to recode everything, meaning every ability, every missile, every attack, everything that could hit the ground.

It already wont work as the ground doesn't change in Z even if you add the terrain deformation, so unless you save the adjusted Z value of every point on the map it's impossible. Also since units can't have negative flying heights, you could only raise the ground up.

Yeah, that is the main problem.

 

[Falafelkorv]

Yeah, this seems impossible... I think we should let this go.
Thanks for the help everyone!
