LittleStain, thank you. You made me understand.

I tried that, but it seems that it does not work, I just don't have clue about what I did wrong:

I Can't believe it can be that easy to use lerp as you explain here. When last time i was asking about lerp, they recommended me to read this:

https://www.scirra.com/blog/ashley/17/u ... delta-time (I'm still not finished with that text. It's too deep.)

And they said that this would help me somehow: "lerp(a, b, c) = c * (b - a) + a"

Nobody explained me about what are a, b, and c or why i would need to use that math to do simple animation.

Thats why i "invented" my own method to do animations:

It's easy to set, but takes little more time, because you need to do some variables etc. for your object.

Would this work?

lerp(ObjectName.opacity.0, ObjectName.opacity.100, 0.5)

I don't exactly get how do i need to code these expressions, but i think this can help the topic starter also.

edit: oh wait. I need to write this to the opacity effect itself to the value form.

So it would be like lerp(ObjectName.0, ObjectName.100, 0.5) ?

R0J0hound you're right. Shame on me i was not reading carefully enough.

eliasfrost, I will do that if i got something similar later. This time i know that the error came from %Temp%, because my file size should be something like 30mt, but it became more like 60kt after i accidentally deleted my files from Temp. Lol. ATM its just funny, because i already have almost fixed all damages from one little older backup file. Also because i needed to redo something, i learned few better ways to do some scripts i lost.

Thanks everyone who wanted to help me!

Ashley Some programs could protect their files so you cannot delete them if the files are in use. Could this be done to C2 too?

I had C2 opened when i was cleaning my Temp folder. It probably had some temporary files there and I deleted them. This quite much killed my inspiration. Because so much work lost during this. Maybe i will find it again later. :/

Oh, now i understand. Construct 2 actually saved the whole project and everything into it, to windows Temp folder.... (Why in the name of God it needed to do that... )

I know i cannot save it then, because needed to clean temp to save disc space in C...

I think my game is ready now if there is not any trick to save this... Latest autosave i have, is almost 2 weeks old.

No, i have not moved any files after previous open / close. Also why come it cannot open the project without one png file? It cannot be the last screw that holds the whole boat up.

Yeah, there was some sort of error message at last time i was closing it. If i can remember correctly, it could not build the project because of some shader error. I just cannot remember the details.

Today when i tried to open my project file, it only gave me this error message:

I tried to open it with text editor, but the file is unreadable with it (gibberish). Also that "TiledBackground3.png" is something i have not used in my project for while (it's my first test to do background for the game and when I noticed that it does not look good, i did another sprite as bg). So I don't understand why i still have in that file something that reminds me about that old test after many resaves.

edit: i also tried to open backup file, but it has the same error message.

If you need an animation program, here is your change. <img src="{SMILIES_PATH}/icon_e_smile.gif" alt=":)" title="Smile">
