为什么 String.replace 缩短我的字符串

我制作了一个脚本来动态更改字符串以满足我的需求。它应该可以替换字符串内的标记("[pid]"，"[dir]"，"[+X]"(。但是，我发现 string.replace(( 方法存在一个问题，该方法会切断我的字符串，从而留下重要信息。

下面是最终字符串的外观(放入代码示例中以提高可读性(：

但是，它是这样的：

'summon FallingSand ~ ~4 ~ {Time:1,Data:0,TileID:152,Riding:{id:FallingSand,DropItem:0b,Time:1,Block:minecraft:command_block,TileEntityData:{Command:fill ~ ~1 ~-1 ~ ~-5 ~ air},Riding:{id:FallingSand,DropItem:0b,Time:1,Data:0,TileID:1,Riding:{id:FallingSand,DropItem:0b,Time:1,Data:0,TileID:152,Riding:{id:FallingSand,DropItem:0b,Time:1,Block:minecraft:command_block,TileEntityData:{Command:kill @e[type=MinecartCommandBlock,r=4]},Riding:{id:FallingSand,DropItem:0b,Time:1,Data:0,TileID:1,Riding:{id:MinecartCommandBlock,Command:setblock ~ ~ ~ air,Riding:{id:MinecartCommandBlock,Command:/kill @e[type=Item,r=4],Riding:{id:MinecartCommandBlock,Command:/tellraw @a {text:"Thanks to gentlegiantJGC and xafonyz for making the MCedit filter to make this possible",color:gold},Riding:{id:MinecartCommandBlock,Command:"setblock ~2 ~-2 ~-3 minecraft:redstone_block 0 destroy",Riding:{id:MinecartCommandBlock,Command:"setblock ~3 ~-2 ~-3 minecraft:redstone_block 0 destroy",Riding:{id:MinecartCommandBlock,<b>Com...</b> ~ ~ /execute @e[type=ArmorStand,name=ParticleEmitterDisplay,score_pe_particle_min=3,score_pe_particle=3,score_pe_dir_min=12,score_pe_dir=12,score_pe_ctrl5_min=1,score_pe_ctr5=1,r=32] -2 0.5 0 particle smoke ~ ~ ~ -10 0 0 0.1 0 force",x:43,y:1,z:-79,id:"Control"}",Riding:{id:MinecartCommandBlock,Command:"setblock ~4 ~-2 ~-3 minecraft:redstone_block 0 destroy",Riding:{id:MinecartCommandBlock,Command:"setblock ~4 ~-2 ~-2 minecraft:command_block 1 replace {CustomName:"@",Command:"/execute @a ~ ~ ~ /execute @e[type=ArmorStand,name=ParticleEmitterDisplay,score_pe_particle_min=3,score_pe_particle=3,score_pe_dir_min=13,score_pe_dir=13,score_pe_ctrl5_min=1,score_pe_ctr5=1,r=32] 2 0.5 0 particle smoke ~ ~ ~ 10 0 0 0.1 0 force",x:43,y:1,z:-77,id:"Control"}",Riding:{id:MinecartCommandBlock,Command:buffer,Riding:{id:FallingSand,DropItem:0b,Time:1,Data:0,TileID:157,Riding:{id:FallingSand,DropItem:0b,Time:1,Data:0,TileID:152,Riding:{id:Item,Age:5996,Motion:[0.0,0.0,-0.1]}}}}}}}}}}}}}}}}}}}}}}}}}}}'

这是一个很大的区别，它使我无法使用它。任何已知的解决方法？
