Move unit forward with changing it's angle

[kawas11]

I got a qauestion how to makes unit move forward and changing it's angle using radians.

here is about what i am talking about:

I am not really good with math, but I think using SIN and COS make that kind of pattern.

It's possible to do it without it as well but I imagine that it gets complicated then

 

[kawas11]

moving forward is rly not problem xD

it SetUnitPosition (unit, unitx + speed * Cos(angle), unity + speed * Sin(angle)

the onlt problem i got is to change angle during unit move to make it move like on that image

 

[Chaosy]

native SetUnitFacing takes unit whichUnit, real facingAngle returns nothing

or

• Unit - Make Your unit face angle facing over x seconds

to get the angle itself it's AngleBetweenPoints in jass I think.

I got a qauestion how to makes unit move forward and changing it's angle using radians.

All of the Cos, Sin and Tan as well as their opposite functions use radians. Only unit facing is in degrees. As you are aware you can convert degrees to radians and visa versa using a constant.

Ok, i was trying to do it and i am close but it's not that i am trying t do.

At this moment missle is truning back and moving as i wanted but backward.

set adjustedAngle = angle + Sin(TimerGetElapsed(t) * FREQUENCY) * WAVELENGTH
call SetUnitX(GetUnitX() + speed * Cos(adjustedAngle))
call SetUnitY(GetUnitY() + speed * Sin(adjustedAngle))

With your help i made it to move left or move right every some time and it works as i wanted big thanks

if dat.ang_cd > dat.ang_ccd then
                set adjustedAngle = dat.angle + Sin(TimerGetElapsed(TIMER) * 2.0) * 10.0
                call BJDebugMsg("first")
                set dat.ang_ccd = dat.ang_ccd + INTERVAL
            else
                if dat.ang_cd2 > dat.ang_ccd2 then
                    set adjustedAngle = dat.angle + Sin(TimerGetElapsed(TIMER) * 2.0) * - 10.0
                    call BJDebugMsg("second")
                    set dat.ang_ccd2 = dat.ang_ccd2 + INTERVAL
                else
                    set dat.ang_ccd = dat.ang_ccd - dat.ang_cd
                    set dat.ang_ccd2 = dat.ang_ccd2 - dat.ang_cd2
                endif
            endif
