how to do a missile spell?

[Dracula]

Hi, i wanted to try to do a missile spell like in many maps, in those gun maps etc, you shoot and missile comes out and dmg your enemy, the missile goes straight in front of the caster.

 

[Just_Spectating]

u use dummy units and triggers, this problem is solved many times. search it please. "PoTm's Elune Arrow"

 

[Need_O2]

aaaa shockwave ?, crushing wave ?, carrion swarm ?, breath of fire ?
I guess they will look like shooting if you make missle speed fast and projectile art a bullet one

 

[Dracula]

yea but it will damage all unit in the area, i wanted the elune arrow Just_Spectating said, but it doesnt seem i could do it without jass.

 

[PurplePoot]

You can, but you could only have one bullet on the field at once... There are ways you could have more, but either way it would be far laggier anyways.

 

[Need_O2]

My solution with GUI

well making elune arrow
you need 2 GUI triggers, 3 variables, 1 dummy unit

It has Locust ability
Fly moment type
Moment speed that missle should have
Missle projectile model

A Point variable named TempLoc
An Unit variable named TempUnit
An Unit Group variable named MissleGroup

[trigger="First Trigger"]Missle Lunch
Events
Unit - A unit Starts the effect of an ability
Conditions
(Ability being cast) Equal to <Your Missle Ability>
Actions
Set TempLoc = (Position of (Triggering unit))
Unit - Create 1 <Dummy Missle Unit> for (Owner of (Triggering unit)) at TempLoc facing Default building facing degrees
Unit Group - Add (Last created unit) to MissleGroup
Custom script: call IssuePointOrder(bj_lastCreatedUnit,"move",GetUnitX(GetTriggerUnit())+Cos(GetUnitFacing(GetTriggerUnit())*bj_DEGTORAD)*5000,GetUnitY(GetTriggerUnit())+Sin(GetUnitFacing(GetTriggerUnit())*bj_DEGTORAD)*5000)
Custom script: call RemoveLocation(udg_TempLoc)
Custom script: call DestroyGroup(bj_lastCreatedGroup)
[/trigger]
[trigger="Second Trigger"]Missle Check
Events
Time - Every 0.50 seconds of game time
Conditions
Actions
Unit Group - Pick every unit in MissleGroup and do (Actions)
Loop - Actions
Set TempLoc = (Position of (Picked unit))
Set TempUnit = (Picked unit)
Custom script: set bj_wantDestroyGroup = true
Unit Group - Pick every unit in (Units within <Missle Area (200 would be fine)> of TempLoc) and do (Actions)
Loop - Actions
If (All Conditions are True) then do (Then Actions) else do (Else Actions)
If - Conditions
(TempUnit is alive) Equal to True
((Picked unit) is A structure) Equal to False
((Picked unit) belongs to an enemy of (Owner of TempUnit)) Equal to True
Then - Actions
Unit Group - Remove TempUnit from MissleGroup
Unit - Cause TempUnit to damage (Picked unit), dealing <Your Damage> damage of attack type Spells and damage type Normal
Unit - Kill TempUnit
Else - Actions
Custom script: call RemoveLocation(udg_TempLoc)
[/trigger]

This seems fine to me

 

[Dracula]

but it would move on 522 max speed right? gun missile are more like 1500, but ty for the help too

 

[GhostWolf]

You can enter whatever number you want with clicking on Shift and double clicking on the Speed Base (works with every value in the object editor).

Actualy not any number, its up to 1,000,000,000

 

[Eleandor]

522 is sadly, the fastest a unit can go...

 

[GhostWolf]

Putting more doesn't help ? because in other things (attributes, life, and mana, for example) it does.

 

[Need_O2]

Hmm then change timer interval to 0.03 and make projectile change position in timer trigger overtime

AND REPLEACE
[TRIGGER="THIS"]Set TempUnit = (Picked unit)
Custom script: set bj_wantDestroyGroup = true[/trigger]
[TRIGGER="WITH THIS"]Set TempUnit = (Picked unit)
Custom script: call SetUnitX(GetEnumUnit(),GetUnitX(GetEnumUnit())+Cos(GetUnitFacing(GetEnumUnit()*bj_DEGTORAD)*<speed>*0.03)
Custom script: call SetUnitY(GetEnumUnit(),GetUnitX(GetEnumUnit())+Cos(GetUnitFacing(GetEnumUnit()*bj_DEGTORAD)*<speed>*0.03)
Custom script: set bj_wantDestroyGroup = true[/Trigger]Then change <speed> fileds

AND

[trigger="THIS"]Custom script: call IssuePointOrder(bj_lastCreatedUnit,"move",GetUnitX(GetTriggerUnit())+Cos(GetUnitFacing(GetTriggerUnit())*bj_DEGTORAD)*5000,GetUnitY(GetTriggerUnit())+Sin(GetUnitFacing(GetTriggerUnit())*bj_DEGTORAD)*5000)[/trigger]
[trigger="WITH THIS"]Custom script: call RemoveLocation(udg_TempLoc)
Custom script: set udg_TempLoc = GetSpellTargetLoc()
Custom script: call SetUnitFacing(bj_lastCreatedUnit,bj_RADTODEG*Atan2(GetLocationY(udg_TempLoc) - GetUnitY(GetTriggerUnit()), GetLocationX(udg_TempLoc) - GetUnitX(GetTriggerUnit())))[/trigger]

 

[TKF]

• Custom script: call SetUnitX(GetEnumUnit(),GetUnitX(GetEnumUnit())+Cos(GetUnitFacing(GetEnumUnit()*bj_DEGTORAD)*<speed>*0.03)
• Custom script: call SetUnitY(GetEnumUnit(),GetUnitX(GetEnumUnit())+Cos(GetUnitFacing(GetEnumUnit()*bj_DEGTORAD)*<speed>*0.03)

These doesn't work when you trying to save the map.... there's something wrong with them...

 

[Need_O2]

ups yuea you are right
[trigger="This is ok"]Custom script: call SetUnitX(GetEnumUnit(),GetUnitX(GetEnumUnit())+Cos(GetUnitFacing(GetEnumUnit())*bj_DEGTORAD)*<speed>*0.03)
Custom script: call SetUnitY(GetEnumUnit(),GetUnitY(GetEnumUnit())+Sin(GetUnitFacing(GetEnumUnit())*bj_DEGTORAD)*<speed>*0.03)[/trigger]
dont forget to change <speed>'s

 

[TKF]

Ok, if I want to move this "bullet" every 0.05 sec, and want a speed of 1000. Can I put 50, instead of <speed>*0.03 value?

Like this? So this will move the dummy in his faced direction. I assume this is working response for picked unit.

• Custom script: call SetUnitX(GetEnumUnit(),GetUnitX(GetEnumUnit())+Cos(GetUnitFacing(GetEnumUnit())*bj_DEGTORAD)*50)
• Custom script: call SetUnitY(GetEnumUnit(),GetUnitY(GetEnumUnit())+Sin(GetUnitFacing(GetEnumUnit())*bj_DEGTORAD)*50)

Edit_

I didn't see the projectile traveling using this. What's wrong here?

 

[Need_O2]

:/ Idk it should work
check where you put it

 

[GhostWolf]

If you are instantly moving the units you can just use normal GUI.

 

[Dracula]

i found that GUI cant have too many triggers running at the same time, it slows down, but if i have to do it in jass, then i would forget it, i know jack about jass and dont have the time to learn it :\

 

[TKF]

:/ Idk it should work
check where you put it

I put it in the first loop. But the problem is, that it doesn't seem to work like instant move, not visible at least. Maybe a different MUI JASS code if possible....


I attempted to make a fireball, that explodes on impact, But I must make it MUI, which I doesn't know how. So far I made this...

This is just a fireball kind of projectile.

 

[GhostWolf]

Damd need the bullet thing too >.<

 

[Need_O2]

yours seems ok
I didnt pay much attention while checking

If you want me to give you a JASS code I dont make regular jass triggers anymore. Only vJass triggers that Jass NewGen supports

 

[TKF]

sry I was unspesific. I meant a MUI script, that allows MUI of the trigger.

• --- This part make it non-MUI ---
• Set MagmaBall = (Picked unit)
• Set TempPoint = (Position of (Picked unit))
• Set TempPoint2 = (TempPoint offset by 50.00 towards (Facing of MagmaBall) degrees)
• Unit - Move MagmaBall instantly to TempPoint2

This prevents MUI. Your script doesn't make it instantly move so the eye can see it's projectile movement... I tested with it and could't see it's projectile movement Is there another instant move script that doesn't leak and make the projectile move visible at least...

Don't don't write JASS, so I have no idea about scripts....



1. Keep the trigger as it is (not MUI and quite leakfree)
2. Apply only to all picked units in group move and move them all together (MUI, but much more location leaks pr second)

3. Another solution....

 

[Need_O2]

your trigger is MUI already

you dont transfer single variables to another triggers
you dont use waits etc
so it is full MUI
(well these arent the only things that makes trigger MUI but it is full MUI anyway)

Unless you dont use variables with waits you dont need to fear of anything

I'll tell you what
if 9999999999999999999999999999999999999999999999999 casters casts this spell at sametime
only bad thing will happen is lag


About Moment: Really strange it should appear like projectile moment for a 0.03 timer

 

[TKF]

Doesn't point variables store only 1 point at the time?
Doesn't unit variables store only 1 unit at the time?

You have to explain this to me.... (Cuz I assumed those variables could only store 1 value at the time... not for every projectile in movement...) Maybe I learn something new ^^...

___________

About Moment: Really strange it should appear like projectile moment for a 0.03 timer

?? huh? I use 0.05 timer in my trigger...

 

[Need_O2]

but you use variable right after you change it
so there is no moment between set and use
so nothing can change the variable while you are using it

Since you change variable in every usage it should be a problem

And since we are using unit group to store projectiles it can store-use more of them

 

[TKF]

_______________

Since you change variable in every usage it should be a problem

There's problem with what? Changing the values of variables every time trigger fires? Or did you miss the "'nt"

_______________


But If I understand my own system correct, only 1 projectile at the time can explode on every trigger fires. That would be that 2 fireballs colliding to each other, will not make both fireball explodes at same time. 1 will survive and travel on.... -.-

I'm wrong here in my assessment?

 

[Need_O2]

AH SORRY It shouldnt* be a problem
damn I hate myself

hmm colliding 2 fireballs yea 1 one survive and travel on
add them locust or game other one explode too if its a fireball

 

[TKF]

I just add in the second loop (detect enemies)

If picked enemy unit is a fireball -> give it 0.01 expiration timer -> problem solved.

 

[Need_O2]

cool
