bounec after collision

[ajater]

I am looking for a away to make the player bounce and return back a little bit when he collide with wall, I tried using the bounce function but it make the player flip after collision with the wall,

any help will be appreciated.

Could you please be more specific?

How is your object moving?
How should he bounce? Completely elastic without rotation?
What do you mean with "the bounce function makes the player flip"?

My best guess is that your image_xscale changes according to the hspeed, OR, the sprite rotates according to the direction that is moving, either way, all you have to do is remove that piece of code.

If you want to make the object lose speed after bouncing, all you have to do is put this alongside the bouncing script:

speed*=DAMPING_VALUE //Can be between 0 and 1, 0 will completely stop the object, and 1 will not change the speed at all.

How is your object moving?
the object moving is a car,

How should he bounce? Completely elastic without rotation?
if the car hit the wall from any side it should just return back without rotation,

What do you mean with "the bounce function makes the player flip"?
when I hit the wall the car or the player flip horizontally

Can you give the object information of the car object?

The code that flips the car horizontally lies somewhere else.

I am using this, in the collision event with wall:

When editing an object, there is a button with "Object information" on it.
If you click on it, you get a new window with text in it.
This is the object information.
Copy paste it here.

Information about object: obj_car
Sprite: sprite5
Solid: false
Visible: true
Depth: -100
Persistent: false
Parent:
Children:
Mask:
No Physics Object
Create Event:
execute code:

global.sp_max = 10;

hp = 100;

global.sp_gain = 0.3;

global.handling = 5;

image_speed = 0;

friction = 0.05;

That object information is incomplete.
Please, select the entire text (Ctrl + A) first before copy pasting it.

Although, I actually probably don't need the other code.
You're probably setting image_angle to direction every step.
When you counce off a wall, you change direction, so your image_angle would change as well.
If you line things up correctly, it can result in looking flipped (while its actually rotated 180 degrees).

You should control direction and image_angle seperately.
That, or you use negative speeds.

I solve it, I used this code at the collision event:

if (direction == 0){direction = 90}
else if(direction == 90){direction =270}
else if(direction ==180){direction = 0}
else {direction =180}

I'm glad to hear it got solved!

It could be handy for other people though if you also mentioned how you solved it.
Also, if you haven't done so already, mark this topic as solved.
