[SOLVED] Game speed - animations and code

angel999 · March 31, 2019, 7:02pm

Hi guys ,any one know if there is any way to slow down the whole game ? .
Like lets say i want a slow motion for the game , i have my internal clock in uppdates .
But i dont know how could i slower down ALL the game at once ,like all animations and more .
I know its possible to set animation speed , but i have soo many chanels and listeners …
I suppose all the engine is updated at some speed ,that is took by normal flow of all chanels and rest
of functions ,soo i would like to know how to get it and possible manage it without blow the world up.
Gaming and realty .

I’m not sure of the repercussions, though. Personally I’d set my own just to be sure.

github.com

jMonkeyEngine/jmonkeyengine/blob/master/jme3-core/src/main/java/com/jme3/app/SimpleApplication.java#L141


/**
 * Returns the applications speed.
 *
 * @return The speed of the application.
 */
public float getSpeed() {
    return speed;
}
/**
 * Changes the application speed. 0.0f prevents the application from updating.
 * @param speed The speed to set.
 */
public void setSpeed(float speed) {
    this.speed = speed;
}
/**
 * Retrieves flyCam
 * @return flyCam Camera object
 *

The code is right there if you just search for ‘speed’ in the file already provided.

github.com

jMonkeyEngine/jmonkeyengine/blob/master/jme3-core/src/main/java/com/jme3/app/SimpleApplication.java#L249


    // call user code
    simpleInitApp();
}
@Override
public void update() {
    if (prof!=null) prof.appStep(AppStep.BeginFrame);
    super.update(); // makes sure to execute AppTasks
    if (speed == 0 || paused) {
        return;
    }
    float tpf = timer.getTimePerFrame() * speed;
    // update states
    if (prof!=null) prof.appStep(AppStep.StateManagerUpdate);
    stateManager.update(tpf);
    // simple update and root node
    simpleUpdate(tpf);

so 1 = normal, 0 = stopped completely.

Thank you , i did gave a look but was still uncertain , dont want to break some code i did not created .

Thank you for help

i have my internal clock in uppdates

?

please note, all your code need to be based on tpf(time per frame), otherwise your code that is not based on tpf will be not affected by game speed and will work different for each computer.

you need use tpf in all your code that need be affected by time.

Yeah ,its all fine from that side , i made a clock based on tpf , i just did not wanted to do all actions each round ,soo made a clock that runs some actions once each minute second or hour . And needed some clock as well , but its all based on tpf .

ah, got it. i have something similar to avoid code duplication for a time delayed actions(that take a lot cpu/ram) there is something like this already in JME anway but i dont remember what was it. There is also a queue in jme (but it runs in next frame) but its good for synchronize some calls

then everything is fine.
