[0024] In order to better explain the present invention for easy understanding, the present invention will be described in detail below with reference to the drawings through specific implementation manners.

[0025] Embodiment 1

[0026] Please refer to Figure 1 , an efficient touch allocation method based on cocos2dx, including the steps:

[0027] S1. Create a root node and bind event monitoring;

[0028] S2. Divide the current scene in a preset direction, delimit N regions, create a table with a length of N, and save the abscissas of all child nodes of the root node into the table.

[0029] Step S2 is specifically as follows:

[0030] Divide the current scene equally in width with a fixed pixel interval length horizontally, delimit N regions, create a table with a length of N in memory, and save the abscissas of all child nodes of the root node into the table.

[0031] S3. When a touch operation of the user is monitored through the root node, perform multi-level screening on all child nodes according to the data in the table and preset rules to obtain a target node, and assign the touch event of the root node to the target node.

[0032] Step S3 includes:

[0033] S31. When a touch operation of the user is monitored through the root node, perform a first screening according to the data in the table to obtain all child nodes in the region corresponding to the abscissa of the touch operation.

[0034] S32. Perform a second screening according to all child nodes in this region, respectively judge whether the coordinates of the touch operation are located within the bounding boxes of each child node in this region. If so, record and obtain a set of child nodes.

[0035] S33. Obtain the node with the highest priority according to the levels and rendering sequences of each child node in the set of child nodes, and use it as the target node.

[0036] S34. Assign the touch event of the root node to the target node.

[0037] Embodiment 2

[0038] The difference between this embodiment and Embodiment 1 is that this embodiment will further illustrate how the above-mentioned efficient touch allocation method based on cocos2dx of the present invention is implemented in combination with a specific application scenario:

[0039] 1. Create a root node and bind an event listener, which is also the only touch event listener in the current scene. The rest of the sprite nodes in the scene are child nodes of the root node.

[0040] 2. Divide the current scene equally in width with a horizontal INTERVAL_LENGTH (fixed pixel interval length), delimit N regions, and create a table (mapTable) with a length of N in memory for saving data.

[0041] 3. When initializing the scene, obtain all the child nodes of the root node, calculate the area where each child node is located by rounding down the x - coordinate of each child node divided by INTERVAL_LENGTH, and then save it to the corresponding position in the mapTable;

[0042] 3.1. When a touch operation of the user is detected through the root node, perform a first - stage screening according to the data in the table to obtain all the child nodes in the area corresponding to the abscissa of the touch operation;

[0043] 3.2. Perform a second - stage screening based on all the child nodes in this area, and respectively determine whether the coordinates of the touch operation are within the bounding boxes of each child node in this area. If so, record the obtained set of child nodes;

[0044] 3.3. According to the levels and rendering order of each child node in the set of child nodes, obtain the node with the highest priority and use it as the target node;

[0045] 3.4. Assign the touch event of the root node to the target node.

[0046] Specifically, first, through the first - stage screening, determine which nodes are in the area corresponding to the x - coordinate of the touch operation. Then, through the second - stage screening, determine which nodes' bounding boxes the coordinates of the touch operation are within. Finally, through the third - stage screening, obtain the node with the highest priority according to the levels and rendering order of the nodes. Through multi - level screening, the efficiency and speed of touch allocation are improved.
