How do randomization of a spray x and y according to the angle

How to adjust the randomization of a spray x and y according to the angle I imposed...

As soon as when turning the angle this mechanic does not work...

Is there any way to adjust maybe with sine and cosine ? but I don't know how to test with this formula.

Set bullet angle of motion to targetAngle + random(-1*coneoffire/2,coneoffire/2)

Thank you, Did you understand me?

This is the problem...

No, guess I did not understand.

I don't understand the problem either, even have a picture.

Why don't you want to use a particle. It gives you great customization.

I'm using particle to create fire when it's up (270) it generates a perfect line of fire... randomization x 50px...

When I need to turn 90 degrees, the fire doesn't turn together.... It looks like in image 2....

Oh I see. In that case you probably want to make your own custom particle effect, you'll have much more control.

Create a particle sprite object with fade and bullet behaviors. Spawn at interval as desired and set the bullet angle of motion as I described earlier.

Thank you, I preferred to check the angle of the particle and set the randomization accordingly...

If it's 0 (looking right) randomization x will be 0 and y will be 50...

This need was for my game below...
