c# - "Cannot Implicitly convert type 'float' to 'int'" even when I'm not using any ints -


here's code:

float smoothnoise(float x, float y) {     float fractx = x - (int)x;     float fracty = y - (int)y;      float x1 = ((int)x + noisewidth) % noisewidth;     float y1 = ((int)y + noiseheight) % noiseheight;      float x2 = ((int)x + noisewidth - 1f) % noisewidth;     float y2 = ((int)y + noiseheight - 1f) % noiseheight;      float value = 0f;      value += fractx * fracty * noise[x1, y1];     value += fractx * (1f - fracty) * noise[x1, y2];     value += (1f - fractx) * fracty * noise[x2, y1];     value += (1f - fractx) * (1f - fracty) * noise[x2, y2];      return value; }

the errors occur on these 4 lines:

value += fractx * fracty * noise[x1, y1]; value += fractx * (1f - fracty) * noise[x1, y2]; value += (1f - fractx) * fracty * noise[x2, y1]; value += (1f - fractx) * (1f - fracty) * noise[x2, y2];

as can see, ints use explicitly casted, i'm confused thinks i'm trying implicitly convert int.

i should mention there 8 identical errors of kind, 2 each of 4 lines. boggles mind.

noise array of type float[,]

you're trying use float values array indexer in code fragments like: noise[x1, y1].

array indexers can integers in .net, you've declared them float x1, y1.
