Circle Movement

[xhunterko]

Okay, I've googled about an hour or so now and I can't seem to find something satisfactory. And I KNOW I've seen this before on this forum or in a repository but I can't remember where exactly. So, what I'm looking for is:

How do I get one sprite to orbit/circle around another sprite?

Something with FlxTween would be fine I think, but I'm more looking for something done without the tween. What I want it to do, is have it circle tightly around a sprite, then circle outward as the mouse is held down. And I'm not sure if I can do that with FlxTween.

Any help?

I think you want something like this...

var radius:Int = 100;//circle radius

var ang:Float = 0;

var speed:Float = 0.5;

function update():Void {

   obj2.x = obj1.x + radius * Math.cos(ang);

   obj2.y = obj1.y + radius * Math.sin(ang);

   ang += speed;//you can multiply this to FlxG.elapsed to a constant velocity

   //you can reset ang to 0 when it is over than 360

Well, that works, thanks! Buuuuuut the collisions are now broke.

I am doing this:

override public function update():Void
{

//etc
///
//Hitting Mob
        //FlxG.overlap(ChainGun.group, enemyGroup, playerHitEnemy);    
        FlxG.collide(PlayerChainBall, enemyGroup,playerHitEnemy);    
        FlxG.collide(PlayerChainBall, enemyGroup);
       

        //Checking to see if pixel perfect collisions would change anything
        for (obj in enemyGroup.members)
            {
                if (FlxG.pixelPerfectOverlap(PlayerChainBall, obj))
                {
                    FlxG.collide(PlayerChainBall, enemyGroup,playerHitEnemy);    
                }
            }

//etc
super.update();

}

///etc

/////

//Enemy getting hit by player bullet
    private function playerHitEnemy(playerBullet:FlxObject, enemy:SlimeClasses):Void
    {    
        FlxG.sound.play("Splat", 0.95);
       
        enemy.health -= 1;        
        enemy.bonked = true;
       
        if (enemy.health <= 0)
        {
            particleEmitter.x = enemy.x + 8;
            particleEmitter.y = enemy.y + 8;
            var i:Int;
            for (i in 0...10) {
                var particle:FlxParticle = new FlxParticle();
                particle.makeGraphic(2, 2, FlxColor.RED);
                particle.visible = false;
                particleEmitter.add(particle);
            }
            particleEmitter.start(true, 2, 0, 10, 1);
           
           
           
            //if (enemy.SlimeClass == 0) money += 4;
            //if (enemy.SlimeClass == 1) money += 16;
            //if (enemy.SlimeClass == 2) money += 80;
           
            enemy.kill();
            enemyGroup.remove(enemy, true);
        }
    }

And I am getting this:

Anyone have any ideas on how to improve collisions here?

I solved the issue using overlap instead of collision. Thanks again for your help!
