Maximum size of a map.

[tavaresgeon]

Hello, friends.

I am developing an “RTS-Colony” type game. I have a map that will have an approximate size of 762x1101. The ratio is being 1 = 1m.

I have seen some posts that after 1.000 there are certain problems to calculate float and such. Should I avoid exceeding the size of 1000?

We need a native origin shifter feature to move everything keeping the camera at 0,0,0 when the player moves far than 999 units! This is because the floating point used has only 7 digits. After 999 units (1000 to 9999) we get only three decimal digits… Then the camera shakes, shadow blinks, smaller objects appear out of place… That’s so bad

That size is likely to be fine. I have 2500x2500-sized levels on my Jetpack Kurt game.

However, look up floating point precision / accuracy to see the issues involved.

The wikipedia article on IEEE single precision float may help you visualize the issue as well:
