Now I'm beginning to do a isometric map with some tiles that I have!

I removed the "if(redraw) {" and add the "if (al_event_queue_is_empty(event_queue)) {" in your place for put the "map_draw();" , but I think this did not the right way! ...

Jefferson Almeida said: Edit1: I can add my "map_draw();" in the "if(redraw){" or I have to create a class for him and to do it work with the "current->" ? Yes, just add map_draw() to the 'if (redraw)' block. Jefferson Almeida said: I removed the "if(redraw) {" and add the "if (al_event_queue_is_empty(event_queue)) {" in your place for put the "map_draw();" , but I think this did not the right way! Think about it - do you want to redraw when the timer goes off, or do you want to redraw when the event queue has been fully processed?

When I used the "if(redraw) {" and add "map_draw();" the movement of the character stayed with a imense lag. I think with the time will to give bug! |

If the character movement is lagging behind, you are either not altering it's position often enough, or you are not redrawing enough. Jefferson Almeida said: I think with the time will to give bug!

Hi, I thought in to create an animation for the character when I press the key F1, but I remember what has many positions: RIGHT, LEFT, UP... has some event that check the last key press for I can to make the animation from him when not in motion. 1#include <map>
