# Instant Map Scroll?

##### Veteran
I need help making the map scroll instantly, almost like a skip. I've set the map to scroll up as fast as it can, but I need something more instantaneous. Is this easy? Did I miss a block that can do this?... Or would i have to code it in?

Use this script call:
Code:
``\$game_map.start_scroll(dir, dist, spd)``
Dir is you your scroll direction (down = 2, left = 4, right = 6, up = 8), dist is how many squares you want to scroll and speed is how fast it scrolls. Change those to fit your needs.

Some testing shows me that you should not use a speed higher than 10. Otherwise it causes issues with the movement.

What kind of issues? Since I have never tested it with such high speed I am curious about it.

@Heirukichi I started my test with the speed at 15. It moved over instantly.
I set on a larger map to move right, down, left a bit, left the rest, and up.
The result was right all the way it could go, down all the way it could go, left all the way it could go, ignoring the second left as there was nowhere else to go, and finally all the way up.
Adjusting the speeds I found that at 10 it moved almost as fast and performed the movements correctly.

It seems that the movement goes faster than the display, so it makes me think it's doing this...

Move right 1 block (29 to go lets say), graphics update, move right 1 block (graphics update incomplete), move right 1 block, (graphics update complete 1 block changed). So the map thinks it has 29 blocks to go but your position has already move 3 blocks.

@Roninator2 well, I am not surprised about that movement being instantaneous with a speed of 15. The formula used to calculate speed is the following
Code:
``2 ** speed / 256``
Since 256 is 2**8 having speed set at 15 means you move by 128 (2**7) each frame. However maybe there is a way to speed up the camera as well, I should check that out. Thank you for the thorough explanation.

Thank you so much! This worked, and it's looking good!

Well I would've honestly liked it to mess up, since my game is supposed to be glitched, but oddly enough I set the speed to 15 and nothing bad happened. It was just an instant shoot across the screen, so it worked out!

When it comes to graphics issues they could be related to hardware too. It is possible that a certain glitch/unwanted behavior only appears when using a certain hardware.

certain hardware.
I suppose... but you would think an i7-4770k cpu with 16gb ram and nvidia gtx 770 2gb card would be fine.

This is my battler placeholder image trying out art styles too I want to fake a backview battle system
I think I will want portraits and battle sprites to be 2D and stick to pixel art for overworld not 100%sure but pretty sure its easier to make pixel art for overworld sprites, events and maps and stuff.
