◆ draw()

virtual void draw ( Renderer *  renderer,
const Mat4 transform,
uint32_t  flags 
)
overridevirtual

Override this method to draw your own node.

The following GL states will be enabled by default:

  • glEnableClientState(GL_VERTEX_ARRAY);
  • glEnableClientState(GL_COLOR_ARRAY);
  • glEnableClientState(GL_TEXTURE_COORD_ARRAY);
  • glEnable(GL_TEXTURE_2D); AND YOU SHOULD NOT DISABLE THEM AFTER DRAWING YOUR NODE But if you enable any other GL state, you should disable it after drawing your node.
Parameters
rendererA given renderer.
transformA transform matrix.
flagsRenderer flag.

Reimplemented from Node.

◆ visit()

virtual void visit ( Renderer *  renderer,
const Mat4 parentTransform,
uint32_t  parentFlags 
)
overridevirtual

Visits this node's children and draw them recursively.

Parameters
rendererA given renderer.
parentTransformA transform matrix.
parentFlagsRenderer flag.

Reimplemented from Node.

◆ setIsolated()

void setIsolated ( bool  isolated)
inline

When isolated is set, the position of the node is no longer affected by parent nodes.

Which means it will be drawn just like a root node.


The documentation for this class was generated from the following file:
cocos2d::DrawNode::setBlendFunc
void setBlendFunc(const BlendFunc &blendFunc)
Set the color mixed mode.
cocos2d::DrawNode::drawPolygon
void drawPolygon(const Vec2 *verts, int count, const Color4F &fillColor, float borderWidth, const Color4F &borderColor)
