Frequently Asked Questions

Q: Can copper golems open all types of doors?
A: Absolutely! Copper golems can open all standard doors in Minecraft, such as wooden and iron doors (when powered), enhancing their usefulness for automation and seamless movement through your builds.

Q: Is a graphics driver update needed for the OpenGL 3.3 requirement?
A: Probably not. OpenGL 3.3 is over 15 years old, and Minecraft has required OpenGL 4.0 since 2017. Most modern systems should be unaffected, but updating graphics drivers can help if you face performance issues.
