问题描述
我在下面的。我加在project.properties以下内容：
I'm following this sample in order to learn about RenderScript. I added the following at project.properties:
renderscript.target=19
renderscript.support.mode=true
sdk.buildtools=23.0.2
我写我的.RS文件时，ScriptC_myfilename在创文件夹，但 android.support.v8.renderscript 产生的无法解析一个类型，所以我增加了 renderscript-v8.jar 位于 SDK /构建工具/ Android为4.4W / renderscript / lib目录作为库（配置构建路径>> >>库添加外部JAR），问题是固定的。
I wrote my .rs file, the ScriptC_myfilename was generated at gen folder but the android.support.v8.renderscript could not be resolved to a type, so I added the renderscript-v8.jar located at sdk/build-tools/android-4.4W/renderscript/lib as a library (configure Build Path >> Libraries >> add External JARs) and the problem was fixed.
在作弄我，我无法编译code，由于这个错误，在上ScriptC_filename.java发现的创文件夹：
After codding, I couldn't compile the code due to this error, found on ScriptC_filename.java at gen folder:
Mesh cannot be resolved to a Type
我搜索一下这个问题，试图找到失踪的类，我不知道，也许手动实现这个类作为我的项目的一部分，这样的Eclipse将被允许进口，并修复错误，但我M有点糊涂了，因为网类没有引用甚至在的。
我也试过在导入 renderscript-v8.jar SDK \\集结TOOLS \\ Android的4.4.2 \\ renderscript \\ lib中，以及添加进口android.support.v8.renderscript.Mesh ，但没有成功。
I also tried to import the renderscript-v8.jar at sdk\build-tools\android-4.4.2\renderscript\lib, as well as add import android.support.v8.renderscript.Mesh but with no success.
我不知道这是否会有所帮助，但是这是我的ScriptC_Snow.java文件（这里的一切都发生了，我并没有修改），该意见是在Eclipse上显示误差
I don't know if this would help, but this is my ScriptC_Snow.java file (everything here was generated, I didn't edit it), The comments is the error showed on Eclipse
public class ScriptC_Snow extends ScriptC {
private static final String __rs_resource_name = "snow";
public ScriptC_Snow(RenderScript rs) {
this(rs,
rs.getApplicationContext().getResources(),
rs.getApplicationContext().getResources().getIdentifier(
__rs_resource_name, "raw",
rs.getApplicationContext().getPackageName()));
}
public ScriptC_Snow(RenderScript rs, Resources resources, int id) {
super(rs, resources, id);

__F32_2 = Element.F32_2(rs);
}

private final static int mExportVarIdx_snowMesh = 0;
private Mesh mExportVar_snowMesh; // Mesh cannot be resolved to a type
public synchronized void set_snowMesh(Mesh v) { // Mesh cannot be resolved to a type
setVar(mExportVarIdx_snowMesh, v);
mExportVar_snowMesh = v; // Mesh cannot be resolved to a type
}
public Mesh get_snowMesh() { // Mesh cannot be resolved to a type
return mExportVar_snowMesh; // Mesh cannot be resolved to a type
}
public Script.FieldID getFieldID_snowMesh() {
return createFieldID(mExportVarIdx_snowMesh, null);
}
private final static int mExportVarIdx_snow = 1;
private ScriptField_Snow mExportVar_snow;
public void bind_snow(ScriptField_Snow v) {
mExportVar_snow = v;
if (v == null) bindAllocation(null, mExportVarIdx_snow);
else bindAllocation(v.getAllocation(), mExportVarIdx_snow);
}
public ScriptField_Snow get_snow() {
return mExportVar_snow;
}
private final static int mExportVarIdx_wind = 2;
private Float2 mExportVar_wind;
public synchronized void set_wind(Float2 v) {
mExportVar_wind = v;
FieldPacker fp = new FieldPacker(8);
fp.addF32(v);
int []__dimArr = new int[1];
__dimArr[0] = 4;
setVar(mExportVarIdx_wind, fp, __F32_2, __dimArr);
}
public Float2 get_wind() {
return mExportVar_wind;
}
public Script.FieldID getFieldID_wind() {
return createFieldID(mExportVarIdx_wind, null);
}
private final static int mExportVarIdx_grav = 3;
private Float2 mExportVar_grav;
public synchronized void set_grav(Float2 v) {
mExportVar_grav = v;
FieldPacker fp = new FieldPacker(8);
fp.addF32(v);
int []__dimArr = new int[1];
__dimArr[0] = 4;
setVar(mExportVarIdx_grav, fp, __F32_2, __dimArr);
}
public Float2 get_grav() {
return mExportVar_grav;
}
public Script.FieldID getFieldID_grav() {
return createFieldID(mExportVarIdx_grav, null);
}
private final static int mExportFuncIdx_initSnow = 0;
public void invoke_initSnow() {
invoke(mExportFuncIdx_initSnow);
}
}
这是我的renderscript code（.RS文件）：
This is my renderscript code (.rs file):
#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++;
}
}
我只用了SDK管理器来获得这些文件，有什么我失踪？任何人都可以给我一个链接到donwload最新版本renderscript-v8.jar的？是否有任何联系，我可以用它来查看丢失的类，以实现它在我的项目，所以Eclipse'd被允许进口和使用它吗？
I only used the SDK Manager to obtain the files, is there anything I'm missing? Anyone can give me a link to donwload the latest version of renderscript-v8.jar? Is there any link that I could use to see the missing class, in order to implement it in my project, so Eclipse'd be allowed to import and use it?
先谢谢了。
推荐答案
您不能rs_graphics.rsh使用支持库。它不支持像rs_mesh，rs_font或rs_program对象*。支持库仅用于访问RenderScript计算。
You can't use the support library with rs_graphics.rsh. It doesn't support objects like rs_mesh, rs_font, or rs_program*. The support library is only for accessing RenderScript compute.
