Issues with rotating sprite solidity and template upload problems

[Rubix Cube]

I've been trying to make a car racer for the SGDK2, and I've been having problems with solidity. Seems to be that the car (the template car, btw) will only stop if it approaches the top of a solid tile head-on. Any other way causes it to squish through. I've also noticed that the sprite will drive off the right border of the map, though not the left. I recall something similar being mentioned for SGDK1 that was caused due to the sprite being taller than the solid tiles. I'm just using 32x32 tiles with the template car, so could modifying this help?

Also, I finished more RPG graphics and have been trying to upload them, But I keep getting this message; "Could not instantiate mail function. " Any help?

Thanks in advance :yes:.

"Could not instantiate mail function. "

Sounds like a PHP error. (Which would mean it's not on your end)

I don't know about the solidity though .

Well, the reason for driving off the right edge of the map is simple enough:

The left edge of the map is at X=0.  If you went further left, you would be going in to negative X values, which you don't want (it screws things up).  However, there's nothing stopping you from going the other way, since there's no solid blocks there.

I'm not sure if you're only seeing this issue because of the solidity not working or if you actually have the race track butting up against the edge of the map.  If the latter is true, you should definitely move it over.  You'll want a column of solid blocks stopping the car from hitting the left edge (and the right edge, top edge, and bottom edge).

Are you using the TopSolidTileShape for the blocks you want to be solid?  Because that certainly sounds exactly like the problem you're having.  If that is the case, switching it to SolidTileShape should fix the problem.

Looks like the mail error is just an error with the notification that it's supposed to send me.  The submissions are still uploaded.  I deleted the first two submissions and approved your third submission.  I also approved a new weather effects upload.  I didn't look at any of these -- let me know if I approved something I shouldn't have.

Good to hear that the graphics upload is fine. :yes:

No, my tiles are not topsolid. I made a 32x32 brick tile and made it 'SolidTile Shape'. Also, I said that you had to hit the top of the tile 'head-on', if you start turning left and right when you're pushing against the block you just kinda slip through. Incidently, this makes covering the east border very difficult. Do sprites still have to be the same size as the tiles to maintain solidity? The car template was rotated inside a 64x64 square.

In my game, the tiles are 16x16 and the moving character is 14x46.  So even if the character is bigger than the tiles, there is no problem.  Some moving monsters are even bigger, some as big as 128x128 and no problem.

I had some solidity issues too at first, but I managed to solve them using some "ReactToSolid" rules before and after the "MoveByVelocity" rule and a "SnapToGround" rule with a threshold of 3 pixels.  I had to try many things before this combination of rules worked.  Try some combinations with these rules, you may find something that solves your problem.

Yep, adding more 'React to Solid' rules after the Acceleration, left turn, and right turn rules seems to make a big difference in performance.
Thanks for the help, everyone. Hopefully the rest of the project goes smoothly.

I'm glad that worked!

1) Only 1 ReactToSolid should be necessary; it should generally be immediately before MoveByVelocity.  In any case, there should be nothing after ReactToSolid before MoveByVelocity that could affect the sprite's velocity except possibly SnapToGround.
2) I don't know if I posted the car sample that I was playing with anywhere, but the car sprite I made has a different size for every sprite state so that the vertical car (which is narrow horizontally) can fit through narrower widths than the horizontal car.  But in order to help control this, you need to use SwitchToState when turning, which will only allow the car to turn to a new state if it doesn't hit a solid in doing so.

Also, I think the PHP mail error when submitting files to sgdk2.enigmadream.com is resolved.
