transition - time in menu.dat

Postby Nahuel » Mon Oct 09, 2017 6:56 pm

My objective is to add some small animations in a menu. dat
It would be just an image transition (like an introduction) before the menu is drawn. Just a couple of images in fade-out and fade-in, using alpha values for the transition.

This would be very simple to do using "time value" in csqc, ypou know, some drawpic + frametime in CSQC_UpdateView. But I can't figure out how I could use time on menu. dat.
There is something like CSQC_UpdateView in menu.dat? I can use something similar to frametime in menu.dat?
Is there any way to code -for example- this: an image displayed for a second, and then becomes transparent. ?????

How can I use time in the. dat menu without using any external data (such as ssqc time)???


I am using darkplaces :)
Any clue is appreciated, thanks :)

float animtime = (time - starttime) * FRAMESPERSECOND;
float frame = floor(animtime);
float alphavalue = animtime-frame; //sawtooth. will reset to 0 any time it would reach 1.0
drawpic(xy, imageforframe(frame), sz, rgb, 1.0, 0); //alpha should be 1-alphavalue if you're using additive alpha.
drawpic(xy, imageforframe(frame+1), sz, rgb, alphavalue, 0);

be sure to check for frame overflows. you'll probably want to just end your animation then. or loop. whatever. your choice.

Thank you guys!
it works like a charm :)

Is it necessary that I reset the time to 0 after some time?
Because I fear that after a few minutes I might be using "numbers" too high (given by get time).

Could there really be a problem with this? Because gettime doesn't seem to stop at any time (even when the client connects to the game) Should I reset gettime at some point? is this possible?

Would it be problematic if someone were playing for example 24 hours and gettime continued? what is its limit?

Thank you again :)
