Sequential Swing timer execution

阅读更多关于 Sequential Swing timer execution

问题 I'm using a Swing Timer to execute animations in my program. In many instances, there are several different calls made to the animate() method at once, with a separate Timer created for each. I know that, because of the way Swing timers are designed, these all get executed together - all my animations occur at the same time. However, there are some instances where I need to wait for one animation to complete to execute another. Is there a way to make Swing timers execute sequentially - one

How do I add a timer in libgdx java?

问题 I am trying to add a timer for power ups in my game. What I am trying to do is change a parameter (like jump height for example) after the player has collided with the power up box but it should only apply for 4 seconds. I have already written the collision coding and have added a random element to choose which power up is activated. I have also added a power up that will not use the timer (adding 1 to the score). Searching google I found code using various methods like Gdx.graphics

Timer firing Tick event with 15 milliseconds delay

阅读更多关于 Timer firing Tick event with 15 milliseconds delay

问题 I'm having a weird problem with timers. As long as I know, the interval property of a timer indicates the delay between loops in which the timer_Tick event will be fired. I had this problem with the exact signature (15 and 16 milliseconds delay) before while programming in Visual Basic. Any timers that I create, fire their tick event with 15 or 16 milliseconds delay. For instance, if I set the interval of my timer to 1 (which means its tick event should get fired 1000 times in 1 second), the

问题 My Program Using open CV with python I am creating a virtual keyboard which uses a tracked object (which at the moment is a blue pen) and when said tracked object goes within the boundary of a rectangle a letter is printed (at this time I only have one rectangle which prints out "A" when the object intersects). This is all working fine however as you can imagine when the object goes within the boundary of the rectangle the letter is printed out multiple times very quickly. My Problem I need a

问题 I came across a timeout function in a product line code which get me really confused: int TestTimeOut(unsigned long Timed_Val1, unsigned long Timed_Val2) { Timed_Val2 = Timed_Val1 + (Timed_Val2 * 200); if (((Timed_Val1 > Timed_Val2) && (sys_msec < Timed_Val1) && (sys_msec > Timed_Val2)) || ((Timed_Val1 < Timed_Val2) && ((sys_msec < Timed_Val1) || (sys_msec > Timed_Val2)))) return TRUE; return FALSE; } And here is how it's used: unsigned long Timeout = sys_msec; #define MAX_TIMEOUT 15L while (
