How do I use different animation when bullet angle changes

  • I have a sprite that has 3 animations: Default, Left and Right.

    Left is a unicorn running toward left. Right animation is similar.

    I am stuck on what condition i need to use to detect when the object hit solid and bounce back and therefore change direction.

    I only care about X direction (left, right).

    I disabled Bullet's 'set angle' because the object can move in any direction but i only have left or right animation.

    Things i have tried:

    1. Check the object's angle between -90 and 90 to detect facing right and else for left.. It always think it is facing right...

    2. remember the object's last X. Basically i have 2 'on every tick' event, and on the first one, compare the last X to current X and if the last X is less than current X, i assume it is facing right. in the 2nd 'every tick' event (it is right below the first 'on every tick'), i update the instance's last X variable. Doesn't work for some reason.

    3. Debugger shows that bullet behavior has vector X but i don't know how i can use it in Event sheet.

    There gotta be an easier way to do this...

    This would work if the set angle propertie of the bullet behaviour wasn't set off..

    You could try this:

    system is between angles : Sprite.bullet.angleofmotion is between sprite.angle-90 and sprite.angle+90

    sprite set animation to "right"

    else

    sprite set animation to "left"
