[Solved] Collision problem

[Spw]

I try to port some simple code from flixel and got problem, my Player start jumping on platform without reason(?) and i cant understand why this happens. Looks like he bounced back, but only in the exact place. Please help, and excuse my english.

here is the code

package;

import flixel.FlxG;
import flixel.FlxSprite;
import flixel.FlxState;
import flixel.tile.FlxTilemap;
import flixel.text.FlxText;
import flixel.ui.FlxButton;
import flixel.math.FlxMath;

class MenuState extends FlxState
{
	private var thePlayer:FlxSprite;
	private var simpleTilemap:FlxTilemap;
	
	override public function create():Void
	{
		super.create();
		FlxG.worldBounds.set(0, 0, 800, 600);
		FlxG.worldDivisions = 8;
		FlxG.camera.bgColor = 0xff646A7D;
		FlxG.camera.zoom = 3;
		
		//Tilemap settings
		simpleTilemap = new FlxTilemap();
		simpleTilemap.loadMapFromCSV ("assets/simpleMap.csv", "assets/images/tiles.png", 16, 16, AUTO);
		
		thePlayer = new FlxSprite(36, 150);
		thePlayer.makeGraphic(20, 20, 0xFFFF0000);
		thePlayer.drag.x = thePlayer.maxVelocity.x * 4;
		thePlayer.acceleration.y = 300;
		thePlayer.maxVelocity.set(120, 300);
		add(thePlayer);
		add(simpleTilemap);
	}

	override public function update(elapsed:Float):Void
	{
		super.update(elapsed);
		FlxG.camera.follow(thePlayer, PLATFORMER);
		thePlayer.acceleration.x = 0;
			if(FlxG.keys.anyPressed([LEFT, A]))
			{
				thePlayer.flipX = true;
				thePlayer.acceleration.x -= thePlayer.drag.x;
			}
			else if(FlxG.keys.anyPressed([RIGHT, D]))
			{
				thePlayer.flipX = false;
				thePlayer.acceleration.x += thePlayer.drag.x;
			}
			if (FlxG.keys.anyPressed([UP, W]) && thePlayer.velocity.y == 5)
			{
				thePlayer.y -= 1;
				thePlayer.velocity.y = -200;
			}	
		FlxG.collide(thePlayer, simpleTilemap);
		FlxG.log.advanced(thePlayer.velocity.y);
	}
}

You can fix the double jump by replacing FlxG.keys.anyPressed([UP, W]) to FlxG.keys.anyJustPressed([UP, W]). That was the only bug that I seen.

@galoyo said in Collision problem:

FlxG.keys.anyJustPressed([UP, W])

Thank you, but double jump is not realy problem. My sprite shaking on 1 pixel up and down. I made gif to show

I see nothing unusual produced from the code you given. Maybe this thread would help.

@DleanJeans Thank you, i actually find the solution 2 minutes ago, and it also has in thread. I swap the variables for collide()

FlxG.collide(thePlayer, simpleTilemap);
to
FlxG.collide(simpleTilemap, thePlayer);

What is your window size and resolution?
