bug: object disappears randomly

[appsdevpk]

Describe the bug

I followed the documents on the site and built the sample game successfully. But a very strange thing is happening, the bean object disappears randomly when touching the ground on load or during game play. I am using firefox latest version on windows 10. Here is my code, https://gist.github.com/appsdevpk/27d199c654e9bd2d89f3c226d126b224

A clear and concise description of what the bug is.

Could you try with lower gravity? If the frame rate is too low, the object may be tunneling through the floor. Did you check the position of the bean once it disappears?

[appsdevpk]

first time the gravity was 1600, and its still disappearing after lowering the gravity to 1000, here is the video of game play. https://drive.google.com/file/d/1mcuZjnS7-Z1Wyeb8IW2Q7uh2tp_1phCc/view?usp=sharing

Is it just the movie? or does it run that slow? Also, what are the coordinates of the bean when it disappears?

[appsdevpk]

its just the movie, i cannot find the coordinates when it disappears

it looks a framerate on your end problem, can you tell us the frame rate (F1 for debug mode) also debug log every frame the player position will help too

[lajbel]

Also browser and device help too

here is the pos i got, { x: 528.1152000000111, y: 317796.730481202 } i am using asus laptop with 24gb ram, Intel(R) Core(TM) i7-6700HQ CPU @ 2.60GHz 2.59 GHz windows 10 and firefox latest version

Do you have the pos.y and vel.y right when it leaves the screen? That y looks very large.

[appsdevpk]

yes thats the right one, and the velocity i am getting is { x: 0, y: 36519.520000000346 }, besides this issue, the lib is awesome, i have tried many libs before and never found any interesting lib

Try making the floor 480 pixels high instead of 48. You're tunneling through the floor and then gaining speed I think. This is due to having a low frame rate. what is weird though, is that there is a velocity limit, so it is impossible to reach the velocity you get if you were using kaplay. Are you sure you are not using kaboom?

[appsdevpk]

i am using kaplay from cdn (https://unpkg.com/kaplay@3001.0.0-alpha.17/dist/kaboom.js), i changed the floor height to 430 but still having the same issue
