How are people implementing "pause" menus?

Damm i deleted an esential function lol.
when u look at my code i only explain the gui clearing for the game but i'm using a second scene manager for the menu as well and u can pause each one individualy and it will be stored in memory for fast access.

Using a state machine doesn't involve saving all the variable and restoring them each time you change the state of the machine. A state machine is all about easily handling different behavior on say some data easily. It's used a lot in interfaces and AI's in games.

I just created a state manager, simular to that on the previus page. However, I use pointers.

I have an abstract class a bunch derived from it. The class's have a "play", "pause", and "update" method.

I then have 2 pointers...lastState and currentState.
Whenever I change states..

Code: Select all

changestate(State *t)
lastState=currentState;
currentState = t;
lastState->pause(); // pause the last state
currentState->update(); //update the scene to the screen before you unpause it.
currentState->play(); //play this state

btw, pause() stops the timer, so only 1 scene animated by the timer would work at a time.

and the above code should be enclosed as a method.
