I am desperate for an answer!!!!

Hi there, can you please show me or direct me to a tutorial on how to make my player shoot bullets from three different angles (0,90,180). I have tried to do this my self but it on shot at 180 degree. Please help.

You need to get the angle of direction, so if you have the start x/y you can add -1, 0 or 1 to get the dx/dy (direction) you want it to go. To go UP, dx is the same as x, dy is y - 1. That's the point straight up from starting point.

something like this.

public function shoot(x:Int, y:Int, direction:String, speed:Int):Void
{
	var dx = x;
	var dy = y;
	
	switch(direction)
	{
		case "left":
			dx += -1;
			dy +=  0;
		case "up":
			dx +=  0;
			dy += -1;
		case "right":
			dx +=  1;
			dy +=  0;
	}
	
	var rangle = radianAngle(x, y, dx, dy);
	
	velocity.set(Math.cos(rangle) * speed, Math.sin(rangle) * speed);		
}

private function radianAngle(x1:Float, y1:Float, x2:Float, y2:Float):Float
{
	return Math.atan2(y2 - y1, x2 - x1);
}

This is just to give you the math needed for the getting the angle. You should change the code to work with your code.

Haxeflixel has a lot of really nice helper functions for things like this.
https://api.haxeflixel.com/flixel/math/FlxVelocity.html#velocityFromAngle

import flixel.math.FlxVelocity;
...
var angle = 90;
var speed = 1500;
bullet.velocity = FlxVelocity.velocityFromAngle(angle, 1500);
