JavaScript Little problem with my javascript code (rpg game)

Hello dear community

I've a little problem with my code and I'm not able to fix it by myself.
It has to do with the game character which is not able to move by w,a,s,d
anymore but as I said, I don't know why.

Maybe you can help me to fix this problem! 😉
The whole code and the used character sprites are shown below.

Kind regards

Lionel

Hi.

Great thing is, that you provided enough code to see to. Bad thing is im at work computer and cant try it out for now.

However, i can suggest few things.

Set parameters positionX, positionY for player. Then add also attributes newPosositionX and newPositionY.

Once w, a, s or d is pressed, just calculate new position for newPositionX and Y. if(w pressed) { newPositionX = positionX - 1};
Once you have checked the keypress from each button, do the collision check. Not before. if(map(newPositionX, newPositionY) === ok to go) then get positionX and positionY values from these newPosi...

This makes your code way more smaller and easier to follow. Just check, is the key pressed or not, nothing more.

You can add paratemer as boolen playerHasMoved etc. that is changed as true if movement happened. This helps with animation loop. If no movement, dont move or try to.
