[Spell] Unit x:y polar offset

[lordsent]

Hi this is an example of what i need to achive. I could try myself but my jngp is crashing because of this trigger.
I just need to move a unit with polar offset everty 0.03 a little bit further. But with set unit x and y because i dont want that the unit forgets the orders.

Untitled Trigger 001
    Events
        Time - Every 0.03 seconds of game time
    Conditions
    Actions
        Custom script:   set bj_wantDestroyGroup = true
        Unit Group - Pick every unit in (Units in (Playable map area)) and do (Actions)
            Loop - Actions
                Set u = (Picked unit)
                Custom script:   call SetUnitX(GetUnitX(udg_u) * Cos(Angle * (3.14159/180.0)))
                Custom script:   call SetUnitY(GetUnitY(udg_u) * Sin(Angle * (3.14159/180.0)))

It's probably crashing because you're using multiplication (instead of addition) which could easily try to put the unit out of map bounds, which is one way to crash the game.

Fix:
call SetUnitX( udg_u, GetUnitX(udg_u) + ( udg_speed * Cos(angle) ) )

SetUnitX/Y needs a unit as first parameter: SetUnitX(whichunit, whichcoordinate)

Also read rulerofiron99's post.

And I don't see a variable called "Angle".

You could use the DEGTORAD bj instead your calculation.

Thanks it work! But i dont understand the degtorad bj. Do i still need to use the cos and sin?

Also i noticed that some times its fails when getting the angle of a unit. I think for example if this units are created on Init.

You write: 3.14159/180
You write this to convert a value from DEG to RAD. (unit facing is in DEG)
You can use the bj_DEGTORAD instead. It is the very same.

call SetUnitX(unit, GetUnitX(unit) + speed*(angle*bj_DEGTORAD))

Also i noticed that some times its fails when getting the angle of a unit. I think for example if this units are created on Init.

I'm not sure what you mean.
