Hey everyone,
there's a strange problem that I encounter when I test a pong came I was creating, which I cant find the solution to.
After I click "Singleplayer" in frame 1, and it takes me to my frame 2, where my single player content is, it works, but if I get too close with my paddle to the ball, then the ball starts bugging out as shown here:
Frame 2 ball bug problem
-- To fix this, I thought of making it so that the "paddle" can not entirely collide with my ball, but I dont know how to do that
When I click "Multiplayer" in frame 1, after it takes me to my frame 3, I programmed both paddles to work, but they dont react to the ball the way that a "pong" game is supposed to work at all, it bugs out much worse.
Frame 3 -- worse ball bug problem
-- I have no idea how to fix this
Here is my code
Frame 2:
/* DECLARE VARIABLES */
var xMove = 5; // variable for ball movement on x-axis
var yMove = 5; // variable for ball movement on y-axis
/* Enter Frame Event
Executes the function fl_EnterFrameHandler defined below each time the playhead moves into a new frame of the timeline.
Instructions:
1. Add your custom code on a new line after the line that says "// Start your custom code" below.
The code will execute when the playhead moves into a new timeline frame.
*/
var score:uint = 0 // variable for starting score
scoreBox.text = String(score);
addEventListener(Event.ENTER_FRAME, fl_EnterFrameHandler);
function fl_EnterFrameHandler(event:Event):void
{
//Start your custom code
// This example code displays the words "Entered frame" in the Output panel.
ball.x += xMove;
ball.y += yMove;
// test wall hits
if (ball.hitTestObject(wallRight)) {
xMove *= -1;
} else if (ball.hitTestObject(wallBottom)){
yMove *= -1;
} else if (ball.hitTestObject(wallLeft)){
xMove *= -1;
}else if (ball.hitTestObject(wallTop)){
yMove *= -1;
} // end wall hits
// test paddle hits
if (ball.hitTestObject(paddle)) {
yMove*= -1;
score +=1;
scoreBox.text = String(score);
} // end paddle hits
// End your custom code
}
/* Move with Keyboard Arrows
