Spike trap, need help

[Kazuga]

Hi, I'm making a spike trap spell, and I need some help. This is as far as I have got:

Spike trap setup
    Events
        Unit - A unit Starts the effect of an ability
    Conditions
        (Ability being cast) Equal to Spike trap 
    Actions
        Set SpikeTrapCaster = (Casting unit)
        Unit - Create 1 EarthSpike mine dummy for (Owner of SpikeTrapCaster) at (Position of SpikeTrapCaster) facing (Position of (Triggering unit))
        Unit - Turn collision for (Last created unit) Off
        Unit - Order (Last created unit) to Undead Crypt Fiend - Burrow
        Unit - Create 1 Spike trap A for (Owner of SpikeTrapCaster) at (Position of SpikeTrapCaster) facing (Position of (Triggering unit))
        Set SpikeTrap = (Last created unit)
        Set SpikeTrapPoint = (Position of SpikeTrap)
        Unit - Turn collision for SpikeTrap Off
        Unit - Add Permanent Invisibility to SpikeTrap
        Animation - Change SpikeTrap's vertex coloring to (100.00%, 100.00%, 100.00%) with 100.00% transparency

Spike trap activate
    Events
        Unit - A unit Is attacked
    Conditions
        ((Attacking unit) is in (Units of type Spike trap A)) Equal to True
    Actions
        Set SpikeTrapvictim = (Attacked unit)
        Unit - Pause SpikeTrapvictim
        Unit - Move SpikeTrap instantly to (Position of SpikeTrapvictim)
        Unit - Remove Permanent Invisibility from SpikeTrap
        Wait 0.50 game-time seconds
        Unit - Add Earth spikes dummy  to SpikeTrap
        If (All Conditions are True) then do (Then Actions) else do (Else Actions)
            If - Conditions
                (Level of Spike trap  for SpikeTrapCaster) Equal to 1
            Then - Actions
                Unit - Cause SpikeTrapCaster to damage SpikeTrapvictim, dealing 300.00 damage of attack type Pierce and damage type Normal
            Else - Actions

The trap is like a mine, it digs underground waiting for an enemy to pass by then it's going to dig up and trap the fool and spike him! (I just love spiking things^^) The trap model file is an orc burrow btw. The real problem right now is that I have no idea how to make the trap event when a unit comes close, I tried with an aura as you can see above, the spike trap aura. It is a buff who only can buff enemy units but I still don't get it how to make the next trigger event to work correctly, hopw you understand what I mean with all this...

 

[Tyrulan]

First of all you need to know how many traps you have, or can have a maximum of.

Set the traps to array and use a "Unit comes within range of" accompanied with "Unit is enemy of owner of trap equal to false"

You may also want to add something like

"If trap = >7 then kill trap[1]

Good luck. It sounds cool.

 

[Kazuga]

Thanks^^ I will try that
>Edit: I'm not that good with arrays since I don't really know what it does. When I ty to set the variable as an array I can't take the trap as an option...

 

[N2o)]

An alternative way, is to check units within the position of the trap, every say 0.25 seconds.

 

[needshelpplz]

ok

an array is a set of the same vairable (real, boolean, integer, units, whatever).

 

[Kazuga]

argh it still doesn't work, take a look at it and see if you can find what's wrong...

You did not order the damage to the units inside that range; because that action is not inside the 'pick every player...' action. Put it in and it should work fine; that if you will have only one trap.

it is within the UG loop from what i can see (hold LMB before at start of Damage action, and scroll directly up. it will be indented the same distance as the Set spiketrapvictim action, which is in the UG loop)

edit: nvm that, forgot that if/then/else indented as well. only problem with that trigger is that units will take huge damage if they stay on the trap sine the trap doesnt seem to be removed

Well, I haven't got to that point yet to remove it since the first part doesn't work yet. But a problem is that they don't take damage at all since the activate trigger doesn't activate

Order the "units"? Didn't he say that the trap entraps "the unit" and not "units"?

 

[R@i_no_Wyrm]

Hmm, changing all the system, make the trap so it can attack. Say 500 - 600 chaos damage.

Then add another trigger so if any unit is damaged and the damage source unit-type is a spike trap, kill the damage source.

Hm could work but then, the damage needs to be around 1-2 because it's still the caster of the mine who has to get the kill and not the mine. But then, can a unit with locust attack? andwhat happens if he get time enough to attack twice? And, a unit who has used burrow can't attack can it?

 

[Flare]

add permanent invisibility to make it so that trap cant be seen

why must caster get kill?

locust units can atk

set cooldown to a high value to ensure 2nd atk wont occur, but thats no issue tbh since if u remove the dummy after it deals damage, it cant atk again.

Caster must get kill because this spell is going to be used in my hero arena and in it you get a kill if you kill another player..

with permanent invisibility the trap will be seen by the caster...

 

[Flare]

set its transparency to 100% and use permanent invis to hide its shadow (if it has one)

make it so that anything owned by the player can score a kill for that player, not just the hero

ok thanks I will try that

 

[Almighty11]

Ok I've made triggers for you that should be working fine. If you want to add it to kills, just check the life when you are about to explode the trap. If it is going to kill it, just add a kill to Player(Integer B).
P.S.: I made this one so you can use this spell with various players at same time and various traps.

Note: You just have to set up Max_spikes to the max number of traps each player can lay at a time.

Its abit long because it checks if each player has a trap; and if he does, checks his traps.

hope it works fine

 

[Kazuga]

I don't really understand how you made this one, would be nice with comments here and there that explained why you did what you did

>Edit: I found the problem to why the trap didn't spawn wich made the other trigger unable to work, so that's fixed but it still don't work correctly. The trap can still be seen even with 100% transperancy and it doesn't want to attack

>Edit: Ok the triggers work expect that you still can see the trap that is going to attack, the other one is the one is the dummy who digs down and creates the little pile. Updated code

 

[Almighty11]

Well basically you just have to edit the actions (where I put the comment for 'Whatever you want trap to do here' ) and the Max_spikes default variable.

Himm are you talking about my triggers? If you need any big changes to it, just say. And what I did basically was just that:

1- Add trap to (array) unit variable;
2- Check if players have traps;
3- If they have, check traps area for someone;
4- If there is, do action.
4b If there isnt, loop.

If you really need more detailed explanation, I'll surely add.

I don't really know what arrays does, only know that the regular is array 1 of some reason still I have seen people using 2700... I also ain't really familiar with "for each Integer A then do..." same with B ofcourse... Would be nice if you could explain a little more detailed
