【问题描述】:
我关注 this sample 是为了了解 RenderScript。我在 project.properties 中添加了以下内容:
renderscript.target=19
renderscript.support.mode=true
sdk.buildtools=23.0.2
我编写了我的 .rs 文件,ScriptC_myfilename 是在 gen 文件夹中生成的,但 android.support.v8.renderscript 无法解析为类型,因此我添加了位于 sdk 的 renderscript-v8.jar /build-tools/android-4.4W/renderscript/lib 作为库(配置构建路径 >> 库 >> 添加外部 JAR),问题已解决。
编码后,由于此错误,我无法编译代码,在 gen 文件夹的 ScriptC_filename.java 上找到:
Mesh cannot be resolved to a Type
我搜索了这个问题,试图找到丢失的类,我不知道,也许手动实现这个类作为我项目的一部分,所以 Eclipse 将被允许导入它并修复错误,但我我有点困惑,因为即使在 android docs 上也没有引用 Mesh 类。
我也尝试在sdk\build-tools\android-4.4.2\renderscript\lib导入renderscript-v8.jar,以及添加@ 987654328@但没有成功。
我不知道这是否有帮助,但这是我的 ScriptC_Snow.java 文件(这里的所有内容都是生成的,我没有编辑它),cmets 是 Eclipse 上显示的错误
public class ScriptC_Snow extends ScriptC {
private static final String __rs_resource_name = "snow";
public ScriptC_Snow(RenderScript rs) {

rs.getApplicationContext().getResources(),

return createFieldID(mExportVarIdx_grav, null);
}
private final static int mExportFuncIdx_initSnow = 0;
public void invoke_initSnow() {
invoke(mExportFuncIdx_initSnow);
}
}
这是我的渲染脚本代码(.rs 文件):
#pragma version(1)
#pragma rs java_package_name(com.mypackage.script)
#include "rs_graphics.rsh"
rs_mesh snowMesh;
typedef struct __attribute__((packed, aligned(4))) Snow {
enter code here
float2 velocity;
float2 position;
uchar4 color;
enter code here
} Snow_t;
Snow_t *snow;
float2 wind;
float2 grav;
int root() {
rsgClearColor(0.0f, 0.0f, 0.0f, 0.0f);
rsgDrawMesh(snowMesh);
return 0;
}
void init() {
grav.x = 0;
grav.y = 18;
wind.x = rsRand(50)+20;
wind.y = rsRand(4) - 2;
}
void initSnow() {
enter code here
const float w = rsgGetWidth();
const float h = rsgGetHeight();
int snowCount = rsAllocationGetDimX(rsGetAllocation(snow));
Snow_t *pSnow = snow;
for (int i=0; i < snowCount; i++) {
pSnow->position.x = rsRand(w);
pSnow->position.y = rsRand(h);
pSnow->velocity.y = rsRand(60);
pSnow->velocity.x = rsRand(100);
pSnow->velocity.x -= 50;
uchar4 c = rsPackColorTo8888(255, 255, 255);
pSnow->color = c;
pSnow++;
}
}
我只使用 SDK Manager 来获取文件,有什么我遗漏的吗?任何人都可以给我一个链接来下载最新版本的 renderscript-v8.jar 吗?是否有任何链接可以用来查看丢失的类,以便在我的项目中实现它,以便允许 Eclipse 导入和使用它?
提前致谢。

你能发布你的 RenderScript 代码吗?
