The Official Blog of Patcoola

I have been playing around with key movement to move an object on the screen when an arrow key has been pressed.

I have four way direction keys and eight way direction keys.

First impressions, the first time I pressed an arrow key, the object moved across the screen at about 10 pixels per second (I think), the object moved at a very slow rate.

If this is true then Java Scripts cycles AKA frame rate is 10. Oh that sucks.

To over come the problem, I have a trigger and intervals system that works around the problem.

The added benefit of the trigger system, can determine if more than one key is pressed at a time, set the frame rate “cycles” per second and can easily stop all key movements in one place.

Java Script has two sets of key maps, Press and Down, both have a different key map.

Maybe in the future I’ll work out a way to dynamically set key events.
