How can we make all the scenes affected by an action special effect? You can use the tree structure to create a ccnode in the scenario, and then place all the objects affected by the special effect in the scenario on this special effect. The following code can achieve this.

We can see that all objects are attached to the node. In addition, when the special effect action ends, the scenario can be restored to normal. You can use schedule to perform real-time monitoring as follows:

As in the Code, if the action ends, the corresponding status will be restored and setgrid will be empty.

The special effects used in test are as follows:

First, use CCG (x, y) to create a grid. A grid attribute is like a matrix, a network line, and a series of squares and matrices. A () grid will run very fast, but it will not look very good. () Will look very good, but in the one1 generation, it will not run too fast. The frame on any screen is renamed as a texture (FBO). The texture is converted to a vertex array, which is converted by the grid effect. Finally, the vertex array is displayed on the screen.

Ccshaky3d: actionwithrange (5, true, CCG (15, 10), T); // The first parameter is the distortion range, the second parameter is the distortion Z axis, and the shard size, the fourth parameter is the interval.

Ccwaves3d: actionwithwaves (5, 40, CCG (20, 10), T); // wavy, 5 is the number of waves, 40 is the amplitude

Ccflipx3d: actionwithduration (t); // flip the X axis

Ccflipy3d: actionwithduration (t); // flip the Y axis

Cclens3d: actionwithposition (ccpointmake (size. width/2, size. height/2), 240, CCG (), T); // magnifier, the parameter is the center point, radius, grid, time

Ccripple3d: actionwithposition (ccpointmake (size. width/2, size. height/2), 240, 4,160, CCG (), T); // The water wave parameter is the center point, radius, number of waves, amplitude, grid, and time.

Ccliquid: actionwithwaves (4, 20, CCG (16, 12), T); // fluid effect, number of waves, amplitude, grid, time

Ccwaves: actionwithwaves (4, 20, true, true, CCG (16, 12), T); // distorted wave, number of waves, amplitude, horizontal sin, vertical sin, grid, time

Cctwirl: actionwithposition (ccpointmake (size. width/2, size. height/2), 1, 2.5f, CCG (12, 8), T); // twist, center, twist number, amplitude, grid, time

Ccshakytiles3d: actionwithrange (5, true, CCG (16, 12), T); // water wave, range, Z axis, grid, time

Ccshatteredtiles3d: actionwithrange (5, true, CCG (16, 12), T); // broken distortion, range, Z axis, grid, time

Ccshuffletiles: actionwithseed (25, CCG (16, 12), T); // scatter

Ccfadeouttrtiles: actionwithsize (CCG (), T); // top and right fades out

Ccfadeoutbltiles: actionwithsize (CCG (), T); // fade out from the left

Ccfadeoutuptiles: actionwithsize (CCG (16,12), T); // fade out upwards

Ccfadeoutdowntiles: actionwithsize (CCG (16,12), T); // fade down

Ccturnofftiles: actionwithseed (25, CCG (), T); // The square disappears

Ccwavestiles3d: actionwithwaves (4,120, CCG (), T); // Square Wave

Ccjumptiles3d: actionwithjumps (2, 30, CCG (15, 10), T); // jump Square

Ccsplitrows: actionwithrows (9, T); // cut rows

Ccsplitcols: actionwithcols (9, T); // cut the column

Ccpageturn3d: actionwithsize (CCG (15,10), T); // flip

I just started to study this engine. If there are any errors, I hope you can correct them more.

Next, let's take a look at other scenarios in the test class.
