Pin didn't work, it only grabs me when I get to the edge of the log.

Nope, I tried turning it on, it didn't change anything.

Thanks for all the help so far I do think that there is a bug with construct so I went ahead and filed a bug report here:

scirra[DOT]com/forum/setting-bullet-speed-to-a-negative-value-inverts-the-result_t149146

Problem Description

When setting the speed of a bullet object through an event, a negative value will invert the result when applied twice.

Attach a Capx

drive.google[DOT]com/file/d/0BwDq5BPaWAXyaWl3NUJqUVlaX00/view?usp=sharing

Description of Capx

Adds a sprite with a bullet behavior. When x is pressed the sprite moves to the left, when pressed again sprite will move to the right, and so on.

Steps to Reproduce Bug

• Open a new Empty Project
• Under Projects window Right Click on Object types, select insert new object
• Add keyboard
• Add a new Sprite
• Upload image or use pen tool to ensure it is visible in some way
• Under Sprite behaviors add bullet
• Set Speed to 200
• Set Initial State to Disabled
• In the event sheet add a new event
• Choose on key pressed, set to "X"
• Add action Sprite, Set Bullet speed to -200
• Add action Sprite, Set Bullet to enabled
• Run Layout
• Press X
• Observe that Sprite moves to the Left
• Press X
• Observe that Sprite now moves to the right
• Observe that pressing X multiple times will repeat this behavior

Observed Result

Sprite inverts it's direction when X is pressed.

Expected Result

Sprite should only move to the Left, repeatedly setting the speed to a negative number should not change the movement once the sprite is moving.

That's a really good idea I'll try it out and let you know.

VIKINGS

I'm using bullet because my normal movement is grid based, so I have a different set up for that. When the player is on a log I want the movement to be smooth so I'm using bullet.

My problem is that this: I set bullet to -200 and my player moves to the left. I set it to -200 again and it starts moving the other way. I'm just setting the value to -200 two different times but I get different results!

If anyone could download the project and see if they could replicate the situation locally I would really appreciate it.

So I've got a little frogger clone I'm building. Everything was going great until I got to the logs bit. The frog is supposed to ride on the logs smoothly while in all other instances he moves on a grid. So, I've had a *lot* of trouble getting this to work and I've got the problem nailed down to this.

When I set bullet.speed of the player to a negative value it appears to invert the previous value.

Example: On X pressed Set bullet speed to -200

Each time you hit X the object reverses his direction.

Event 47 and 48 are where I'm setting the speed of the player.

I really appreicate any help guys I feel like I'm going nuts.
