[edit] Local variable
INT resolution
Resolution is used to alter the precision of the position of processes on screen; the level of precision is defined by the value of resolution.
This simulating of fractions in positions is useful for calculations or animations in need of a high precision in order to work properly. It causes the coordinates of all processes to be interpreted as being multiplied by the value of the local variable resolution, associated with that process. So when a process' graphic is displayed, it will appear as if the process' x and y values were divided by the value of resolution. A resolution of 0
is interpreted as if it were 1
.
[edit] Screen Resolution
The resolution of a screen is the dimensions of the screen in pixels. Fenix' default screen resolution is 320×200 pixels. This can be altered by use of set_mode().
[edit] Example
Process Main() Begin // Set screen resolution to 320x200 with a color depth of 8bit set_mode(320,200,8); // Set the FPS to 60 set_fps(60,0); // Set resolution for this process (try changing it to see the effect) resolution = 1; // Create a 200x200 cyan circle and assign its graphID to the local variable graph graph = new_map(200,200,8); drawing_map(0,graph); drawing_color(rgb(0,255,255)); draw_fcircle(100,100,99); // Set size size = 10; // Set the coordinates at screen position 160,160. x = 160 * resolution; y = 160 * resolution; // Move around in circles while leaving a trail behind Repeat trail(x,y,graph,20*size/100,timer+100); // create a mini reflection of this process, // lasting one second advance(1*resolution); // advance 1 pixel angle+=2000; // turn 2 degrees left frame; Until(key(_esc)) End Process trail(x,y,graph,size,endtime) Begin // Get the resolution of the process calling this one resolution = father.resolution; // Remain existent until the specified endtime was reached Repeat frame; Until(timer>=endtime) End
Used in example: set_fps(), drawing_map(), drawing_color(), draw_fcircle(), advance(), resolution, size, x, y, graph, angle, timer
Here are a few screenshots with different resolutions to display the effect it can have.

The effect is clearly visible, so when you are moving processes with graphics around the screen, you might want to consider using a resolution of at least 10 in those processes.
