Perfectly Straight Path

I've done some searching, but haven't found an answer. I feel like i'm missing something simple.

I'm trying to replicate a right to left behavior like Plants vs. Zombies.

My enemy goes from the start node, to the end node. The nodes are perfectly lined up on the Y in a grid.

But it tends to slope down slightly as it moves along. Not in a straight line.

I've created a simple square "enemy" and gave it a pathfinding behavior.

On start of layout it finds path to the X and Y of the "end" node.

And then On pathfinding path found, it moves along path.

Any help is appreciated!

If you're trying to do something like plants vs zombies then you should really be using 8-direction behaviour with simulate left/right for simplicity of moving left or right across the screen.

No pathfinding required, I mean based on the information that I have, depends if your game is more complicated than it seems. Plants vs zombies is just simulate control left towards the left side of the screen, the action 'simulate control left' moves the enemy as though the enemy is pressing left key.
