Touch Event Problem

Solar2D General Questions/Discussion
#1

Hi,

I have 2 image “right arrow” and “left arrow”. I add 1 touch event for each of the image. The purpose of that touch event is to move the sprite right or left.

Below is the code for left arrow(for right arrow’s touch event i use about the same code just change “left” to “right”)

function touchleft (event)  
 if event.phase == "began" then  
 if gameIsActive == true then  
 pencetKiri = true  
 pencetKanan = false  
 motionx = -speed  
 motiony = 0  
 player:prepare("playerleft")  
 player:play("playerleft")  
 display.getCurrentStage():setFocus(event.target,event.id)  
 end  
 elseif event.phase == "ended" or event.phase == "cancelled" then   
 display.getCurrentStage():setFocus(event.target,nil)  
 end  
end  
left:addEventListener("touch", touchleft)

I found some weird behavior if i do these steps in my arrow:

  1. press left/right arrow
  2. with another thumb pres anywhere on the screen
  3. release the thumb that press left/right arrow

the weird behavior in my case is the sprite keep moving to right/left (by right should stop when the thumb no longer press the arrow).

Any idea what is the root cause and solution for this problem?

Thank You.
