I wanted to make this mod so I could figure out how it all works. I'm having trouble figuring out why it throws a NoSuchMethod Exception. Does the server even keep track of ticking entities?

Why would the server--the authoritative source for all things--not know about ticking entities. Your problem is that the function you're calling only exists on the client: /** * Updates the entity motion clientside, called by packets from the server */ @SideOnly(Side.CLIENT) public void setVelocity(double x, double y, double z) { this.motionX = x; this.motionY = y; this.motionZ = z; } If you want to modify motion on the server, just set the values directly. They're public. Quote Apparently I'm a complete and utter jerk and come to this forum just like to make fun of people, be confrontational, and make your personal life miserable.

Also when I did try to make a entity that extends EntityTNTPrimed, I was confused on weather I need to register a custom entity or if it's just registered when it's spawned. there is a class in com.dna.everythingisbad.entity Quote Link to comment Share on other sites More sharing options...

DavidM Posted August 7, 2019 Share Posted August 7, 2019 34 minutes ago, DeaSTl said: But i'm just wondering why setVelocity is client side only. It is used to update the motion of entities on the client-side. It is used by packets from the server. Quote Some tips: Spoiler Modder Support: Spoiler 1. Do not follow tutorials on YouTube, especially TechnoVision (previously called Loremaster) and HarryTalks, due to their promotion of bad practice and usage of outdated code. 2. Always post your code. 3. Never copy and paste code. You won't learn anything from doing that. 4. Quote Programming via Eclipse's hotfixes will get you nowhere 5. Learn to use your IDE, especially the debugger. 6. Quote The "picture that's worth 1000 words" only works if there's an obvious problem or a freehand red circle around it. Support & Bug Reports: Spoiler 1. Read the EAQ before asking for help. Remember to provide the appropriate log(s). 2. Versions below 1.11 are no longer supported due to their age. Update to a modern version of Minecraft to receive support. Link to comment Share on other sites More sharing options...
