dop2000 This is just a silly example. I will teach you how to recognize where the problem is, the object or plugin to fix. In the case of the example, collision is the problem, so the scirra has created calculations of the whole stage (even outside the camera that is calculating) with the mathematics of to make two solutions, x and y comparison or to make an intelligent collision field that connects and turns off, thus dropping the cpu.
Now each type of object has its tricks to optimize.
Example: data, such as dictionary, array, local storage and others I teach how to create smart update with locks where it deletes loops. So the data is only triggered when needed (based on system start and process death), Ja sounds are based on loop-cuts to optimize them and compression formats, images and sprites with the size that can be cut and spliced not visible. Effects like particles, with cycles and overlapping of time cycles, publishing to see how and where you load and how and where you perform the visualization of it and how you manipulate the cycles of updating it. ajax type internet objects with requesitions.
I will teach you how to solve these problems in order to manipulate any object.
