How do I make the motion of Bullet change?

Hi guys. I need help with the motion of Bullet.

In my game, I change the movement of player by adding a Bullet for the player sprite and changing the angle. But I only can stop the movement of bullet by layout. Could I add some sprites to stop them, if the sprites can go back after crashing the sprites (moving in an opposite direction), it should be better.

In short, could I make the barriers to stop the movement of bullet？

You would simply add a sprite and add an event

"Player: On collision with [Sprite] --> Player: Bullet: Set speed to 0".

But I have a question though:

why would you use bullet for the player movement?

Why wouldn't you use "platform", "custom movement" or "8 direction"?

Thanks for your help. But it still does not work.

I want to keep the player moving, and when I slip the screen, its direction of movement will be changed.

If I set the speed to 0, the player will not keep moving.

So you want to this?

• when you swipe right, the player moves to the right
• when you swipe left, he moves to the left
• when you swipe in any direction while he is moving, he changes directions?

Yes. This is what I want.

Alright, assuming you don't help with the swipe input, this is what you do:

On right swipe:

On left swipe:

(Replace 300 by the speed you want. Alternatively, replace the whole "set speed" to "set acceleration", if you don't want immediate movement)

Thanks, I'll try it.
