So i tried to make grant2 always go to either the x or y coordinate of the next grant one
to determine who the next grant one was I used this post
Tricky situation... Get the nearest object
but there was an error here is my code and the error
java.lang.ClassCastException: class grant2 cannot be cast to class grant1 (grant2 and grant1 are in unnamed module of loader java.net.URLClassLoader @57092432)
at grant.a(grant.java:67)
at grant2.act(grant2.java:17)
at greenfoot.core.Simulation.actActor(Simulation.java:567)
at greenfoot.core.Simulation.runOneLoop(Simulation.java:530)
at greenfoot.core.Simulation.runContent(Simulation.java:193)
at greenfoot.core.Simulation.run(Simulation.java:183)
so yeah hope someone could help me out fast
