That's not rendering bug. Your tileset is somehow damaged, it's not even 32-pix wide (Should be 768, not 766)

I have no idea where you got that one.. Try this instead.

Well. I was not sure either, but it sounded like a right one to try.

Well. X-pos of the arrow looks to be just ok to me. Y-size is somewhat out, and I have to say that reading the equations ain't the easiest.

AHA..

Problem is that your RealImage -sprite has some extra transparent pixels at the top of the image. Image size is higher than the visible area, thus the scaling fails.

Use "crop transparent edges" at the image editor. That seems to image length.

Also.. You can just delete subevents 11 and 12 .. those are not needed at all. Actually it works better without them.

I dont want to be ungratefull but thats just not helpfull at all. I know about manual and Im reading it whenever im in doubts.

I would be very happy for complete answer with directions what to do.

To be fair, it's quite impossible for others to know for sure if someone has read the manual or not. And not all people do.

Overall I think it's possible to solve these problems on special cases, but finding the universal and automatic solution that works on all possible platforms and implementations without great performance overhead is going to be hard.

I have not tested this.. but according scirra.com/manual/126/system-expressions there is ready made function for replacements.

replace(src, find, rep)

Find all occurrences of find in src and replace them with rep.

One things that C2 direly needs is a lot more deeper user manual. The system expressions part is totally inadequate on explaining all the functions available. Especially those Regexp- commands ...

There was an old Tutorial of making pinball game with physics, but unfortunately the files seem to be missing.

I tested this capx and see no real slowdown. I'd like to know what kind of PC you have. OS, GFXcard etc etc .. Especially if it's laptop/Nvidia, since those can be really slow sometimes.

On my desktop PC (6core athlon, W7/64bit, Radeon 78xx) I see no slowdown. Ffox has some frame rate jitter, but chrome is real close to 60fps..

any good ?

Man! Either you are deviously clever, or I've grown stupid. Making object moving FSM using just control points, 1 Event and bullet behavior. <img src="smileys/smiley32.gif" border="0" align="middle">

About the only 100% proof way I see to eliminate tile border issues would be disallowing the Float positioning and scaling entirely.

Unfortunately the float positioning comes from the fact that bowser frame rate ain't stable and thus the object and BG movements can't be kept on exact pixel coordinates if the movement has to look even. And non-float scaling options either cause multiple layouts or wide (ugly) borders.

In a sense it's kinda amazing to think that with all the challenges coders had on old era (like on C64 and Amiga), at least the audio and frame sync was not amongst them. These extra layers of code and helper functions have done a lot of good, but also caused some all different problems.

As far as I have seen .. at least the following ..

• When you post, always take a copy (Ctrl-A + Ctrl-C) before hitting the post/reply button. More often than not the forum software loses the first post attempt.

• Forum does not give visual clue (at the normal pages) that you have private messages waiting.

• Latest-posts system seems to be highly unstable. Time-limit setting does not stick, and can lead missing the posts.

• Timezone setting? something that

  danialgoodwin mentioned above, but I have no clue.

(part II )

I don't consider these any real bugs, merely inconveniences etc.:

• Lack of image posting capability. Is apparently known limitation of software.

• Link posting limits, are part of spam controlling methods used.

• Reputation system is ... well, Odd is word I'd use.

• Visual inconsistencies.. Most pages have green theme but some (older?) are with blue.

• Some general cleanup is needed, at least on tutorials-area. Check of file availability and links being active.

I agree. Even though I have not taken any measurements, I'd expect the sprite/tile with Opacity=0 to cause slightly more menory/gpu/cpu load than using entirely invisible object.
