I'm trying to make a simple Asteroid game with the BGE, using Python when necessary. I want to make 'visible' the ship trails when I press 'W' to increase the speed and make them 'invisible' if 'W' is not pressed. Where is the error? I'm very new with Python scripts.
You can do:
own['trails'] = trailsObject own['trails'].visible = True own['trails'].visible = False
or as i can see in the image:
cont.activate(trails) # to activate the actuator cont.deactivate(trails) # to deactivate the actuator
Also visit the BGE Documentation.
Next time please take a moment to copy your code as text and format it.
