I am making a structure with 4 template pieces .

Sometimes it gen properly like this.

But mostly,it gen like this.

 

 

here is the code https://github.com/HungTeen/pvzmod/tree/dev/src/main/java/com/hungteen/pvz/structure/davevilla

 

and this picture maybe helpful.It shows the place of structure block.

ok,finally i know the problem.

Im just so stupid !

public DaveVillaComponent(TemplateManager manager, ResourceLocation res,BlockPos pos, Rotation rotation) {
			super(IStructurePieceType.SHIPWRECK, 0);
			this.templatePosition = pos;
			this.rotation = rotation;
			this.res=res;
//			this.midPos=blockpos;
			this.setUpTemplate(manager);
		}

I just forgot to change the IStrucurePieceType.SHIPWRECK which I copy from default code.
