本文介绍了生成一个新的随机!的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧! 问题描述 你好codeproject复活节快乐, 我目前正在用随机块生成块,但是, 当我这样做时,整个大块是草,泥土,石头,或空气, 我不知道为什么,这就是我来这里的原因。新随机数总是保持不变 。我不知道为什么,但这令人沮丧,这是我的代码: / * 循环通过块来生成。 * / for ( int i = 0 ; i < Chunk.ChunkWidth; i ++) { for ( int j = 0 ; j < Chunk.ChunkHeight; j ++) { if (Chunk.ChunkY > 0 ) { int r = new Random()。Next( 0 , 4 ); / * 将材料设置为污垢。 * / if (r == 0 ) Block .MakeBlock(BlockMaterial.Material_Dirt); if (r == 1 ) Block.MakeBlock(BlockMaterial.Material_Grass ); if (r == 2 ) Block.MakeBlock(BlockMaterial.Material_Stone ); } else { / * 将块材料设置为空气。 * / Block.MakeBlock(BlockMaterial.Material_Air); } / * 设置块。 * / Chunk.SetBlock(i,j,Block); } } } 解决方案 嗨 试试这个: var randomNumber = new Random(); / * 循环通过块来生成。 * / for ( int i = 0 ; i < Chunk.ChunkWidth; i ++) { for ( int j = 0 ; j < Chunk.ChunkHeight; j ++) { if (Chunk.ChunkY > 0 ) { var r = randomNumber .Next( 0 , 4 ); / * 将材料设置为污垢。 * / if (r == 0 ) Block .MakeBlock(BlockMaterial.Material_Dirt); if (r == 1 ) Block.MakeBlock(BlockMaterial.Material_Grass ); if (r == 2 ) Block.MakeBlock(BlockMaterial.Material_Stone ); } else { / * 将块材料设置为空气。 * / Block.MakeBlock(BlockMaterial.Material_Air); } / * 设置块。 * / Chunk.SetBlock(i,j,Block); } } } 尝试在循环外生成随机数。 / * 循环通过块来生成。 * / for ( int i = 0 ; i < Chunk.ChunkWidth; i ++) { for ( int j = 0 ; j < Chunk.ChunkHeight; j ++) { if (Chunk.ChunkY > 0 ) { int r = RandomNumber ( 0 , 4 ); / * 将材料设置为污垢。 * / if (r == 0 ) Block .MakeBlock(BlockMaterial.Material_Dirt); if (r == 1 ) Block.MakeBlock(BlockMaterial.Material_Grass ); if (r == 2 ) Block.MakeBlock(BlockMaterial.Material_Stone ); } else { / * 将块材料设置为空气。 * / Block.MakeBlock(BlockMaterial.Material_Air); } / * 设置块。 * / Chunk.SetBlock(i,j,Block); } } } 私有 int RandomNumber( int min, int max) {随机随机= new Random(); return random.Next(min,max); } 调试程序并检查 RandomNumber 函数返回的内容 Hello codeproject happy easter,I am currently generating chunks with random blocks, however,when I do this, the whole chunk is either grass, dirt, or stone, or air,I am not sure why and that''s why I came here. The new random always stays the samein the void. I don''t know why but it''s frustrating, here is my code:/* Loop through the chunk to generate. */ for (int i = 0; i < Chunk.ChunkWidth; i++) { for (int j = 0; j < Chunk.ChunkHeight; j++) { if (Chunk.ChunkY > 0) { int r = new Random().Next(0, 4); /* Set the material to dirt. */ if (r == 0) Block.MakeBlock(BlockMaterial.Material_Dirt); if (r == 1) Block.MakeBlock(BlockMaterial.Material_Grass); if (r == 2) Block.MakeBlock(BlockMaterial.Material_Stone); } else { /* Set the block material to air. */ Block.MakeBlock(BlockMaterial.Material_Air); } /* Set the block. */ Chunk.SetBlock(i, j, Block); } }} 解决方案 HiTry this:var randomNumber = new Random();/* Loop through the chunk to generate. */ for (int i = 0; i < Chunk.ChunkWidth; i++) { for (int j = 0; j < Chunk.ChunkHeight; j++) { if (Chunk.ChunkY > 0) { var r =randomNumber.Next(0, 4); /* Set the material to dirt. */ if (r == 0) Block.MakeBlock(BlockMaterial.Material_Dirt); if (r == 1) Block.MakeBlock(BlockMaterial.Material_Grass); if (r == 2) Block.MakeBlock(BlockMaterial.Material_Stone); } else { /* Set the block material to air. */ Block.MakeBlock(BlockMaterial.Material_Air); } /* Set the block. */ Chunk.SetBlock(i, j, Block); } }}Try to generate random numbers outside the loop./* Loop through the chunk to generate. */ for (int i = 0; i < Chunk.ChunkWidth; i++) { for (int j = 0; j < Chunk.ChunkHeight; j++) { if (Chunk.ChunkY > 0) { int r = RandomNumber(0, 4); /* Set the material to dirt. */ if (r == 0) Block.MakeBlock(BlockMaterial.Material_Dirt); if (r == 1) Block.MakeBlock(BlockMaterial.Material_Grass); if (r == 2) Block.MakeBlock(BlockMaterial.Material_Stone); } else { /* Set the block material to air. */ Block.MakeBlock(BlockMaterial.Material_Air); } /* Set the block. */ Chunk.SetBlock(i, j, Block); } }}private int RandomNumber(int min, int max){Random random = new Random();return random.Next(min, max);}Debug your program and check what RandomNumber function returns. 这篇关于生成一个新的随机!的文章就介绍到这了,希望我们推荐的答案对大家有所帮助,也希望大家多多支持! 10-20 23:11
