i followed the tutorial to set JME on eclipse and i think ive done it right because when i run the application , that thing to set resolution is shown , but after pressing ok it just crashes :/…
(this happens at JM platform too)
sorry for my english
and sorry if this is a stupid error, im just using JME for educational purposes as im newbie at JME.
the weird thing is that i download some guy game made in JME and it runs smoothly
You probably selected some antialiasing option (x2, x4, etc) but your hardware doesn’t support it. Just make sure its set to “Disabled”
