Troubleshooting

Today I have been trying to fix some problems I've had with my game. For one when my enemies are in wonder mode (out of the aggro range), they could go through the "crops" however, when they are in follow mode (in aggro range) they can't move in or get into the "crops". This almost drove me into madness until I figured it out, I just need to make the crops in the background instead of an object. but I wanted the enemies to spawn inside of the crops, so I got the pixel measurements and out the spawn inside of them. In the future I want them to change sprite so the player thinks that they are inside of the crops.
