Hello,

I'm having a serious problem with AppGameKit Studio.
Indeed, in the game that I code (knight and demons) when I go from the table editor to the game, the fps goes from 60 to 8.
I'm only doing everything erase and reload
The problem is the same when the character dies and the level is restarted.

obviously, the problem does not appear in agk2 !

is this a problem with deleteallsprite?
A memory problem badly erase?
I do what i do !!!

Hi, Captain Ouais, it has been a long time isn't it ?

For your problem, you could try to switch the engine on OpenGL instead of Vulcan. The last update, add a command for that.

I don't have App Game Kit Studio because I have missed the discount period because of healthy problems, it's sad...I hope you enjoy it

There was a bug that caused slow sprite rendering, can you try the attached version and see if that fixes it?

That can be caused by the window being resized but is more for informational purposes, it is not an actual error.

Thanks to Freddix, the problem has been identified

when deleting sprites with deleteallsprite, my game drops to 7 fps instead of 60
If I delete sprites "manually", no problem

I created a post on github

Thx to all
I do what i do !!!

Hi Crystal Noir, Hi Captain Ouais !
What Captain ouais forgot to mention is that he used DeleteallSprites() and with this method the problem appeared.
But when I suggested him to no more use it and delete sprites one per one, the problem does no more happen.
So, I think that there is a problem with the DeleteallSprites method.

Regards,

Hi Freddix, Hi Captain Ouais,

It seems that TGC should look at this issue because DeleteAllSprites() could be handyi in some cases

@Captain Ouais : didn't see your last post when posting my answer

@Crystal Noir : If this command is Handy, it's a really bad practice to use it.
What I suggested to Captain Ouais, is to create a custom DeleteSprite method working this way :

MyDeleteSprite( SpriteID As Integer )
if getSpriteExists( SpriteID ) = 1
DeleteSprite( SpriteID )
Endif
EndFunction 0

This way you can reset your sprite object ... If for example you have a structure containing player sprite ID :
Type Player_Type
SpriteID As Integer
EndType
PlayerOne As Player_Type

You can reset your sprite using :
PlayerOne.SpriteID = myDeleteSprite( PlayerOne.SpriteID )

With this when you must use your sprite (at any place) just check before that it exists or that it is not equal to 0
