First Shot at a "Dash" Spell

[Waaaaagh]

When NewGen starts at the main menu, it is because you have not saved the map yet. Go into the main editor (terrain), and save your map. Then test it. It will boot directly (and, if you have it enabled, in a window)

EDIT: Hey Sooda!

 

[WarLuvr3393]

I can't follow you're tutorial on the "Dash" it's way too much and It's way too hard to understand. I don't find it simple. This is hella confusing...............................................I'm hating this. I think I might go back to GUI.

worst choice you would ever make...

Edit: Here's my script. I used the HandleVars sytem and tried to mimic your tutorail Emij, it's not working though.

I don't know what I'm doing wrong, like always, this stuff is WAY too hard. And yes, I used the BJ because I'm WAY too lazy to get the formulas, 1 extra formula call won't hurt.

***bump***

I updated the current script and it's still not working. Please help me fix this!

 

[substance]

dood tell us what's happening!

Do the actions run at all? does it give you an error? does your computer blow up when you try to run it?

 

[WarLuvr3393]

When I cast the spell, the unit doesn't get paused, nothing happens. The Raw Code is correct. I don't know what's happening or causing the problem.

 

[WarLuvr3393]

Edit: I fixed a few things and now the unit gets paused, so that's an UP but no movement occurs, the FW_Dash function doesn't work.

*Sorry for the double post, I thought I had editted but I guess I added a reply.

call TimerStart(dashtimer, 0.035, true, function FW_Dash)
call DestroyTimer(dashtimer)

You destroy the timer right after creating it which means its functions wont run. You are supposed to destroy the timer after you're done using it.

call PauseUnit(caster, true)
call SetUnitAnimation(caster, "attack")

[del]I think if you pause a unit you can't set it's animation.. I could be wrong though.[/del] I was wrong, what you did is fine.

call RemoveLocation(targetpoint)

You should null this too.

Also, as a general rule of thumb you should use coordinates instead of locations. Locations are slower and using coordinates is easy if you know what the native location functions do (which you would if you're using TESH or JASS Craft).

>I think if you pause a unit you can't set it's animation.. I could be wrong though.

You are

EDIT:

Here is a simple knockback trigger I made for my map.
The InitTrig function is different to yours, and so is a few other things, as the trigger is for a passive spell, but it gives you the basic idea of how to use X and Ys instead of locs for making a unit slide.

The actions you should pay attention to are in bold:
