so a tip popped up saying that if you update lasers to level 2 you can set a permanent direction for them. I have only been able to pull this off once, usually it does not work. is it disabled in the later levels by design or something? as I understand it to set the direction you hold your finer on the laser in question and then drag a line in the direction you want it to face. whats even weirder is sometimes I do this and it even makes the laser in question explode? uhh..? lol what am I doin wrong or is this a bug?
You should follow me on twitter here!
I have exactly the same problem / question
Yeah, it does say Level 2, but I think it's a Level 3 (twice upgraded), or higher, Laser Tower that can be set in one direction (by double tapping).
Yea, you double tap on the laser tower to lock it into the direction it's currently facing. It can only be done if the tower is on level 3 or higher.
Dragging to make the line on the screen is for joining your tower to a vortex tower. You grab one tower and drag towards a vortex tower and then they're linked.
When a tower explodes accidentally, maybe that happens when a person grabs a tower, drags to make a line, and lets go when they're resting on the "$" button. It could think you're pressing the button.
Upgrade your laser to level 3, when they go double-barrell, then you need to wait until they are pointed in the direction you want them to freeze in and double-tap the tower. Double-tap again to unfreeze (like if you didn't catch it at the right angle).
Dunno about the exploding towers thing...
